They say the best things in life are free, and, man, is that true.

Many of us are coming to the point in our lives where we need to start "adulting." Trust me, I know, it's a terrifying concept to think of, but we can't stay undergrads forever. Now's the time where we need to start - for lack of a better phrase - getting our shit together.

Don't get me wrong, I know that's easier said than done. But that's why I'm here to lend a hand to my fellow reluctant adults. There are all sorts of resources and services out there - for both serious stuff and common every day stuff - that can help us make the transition.

1. Mint

Mint by Intuit is a personal finance service that makes keeping track of all your finances easy. If there's a time when we really need to start focusing on being money-savvy, it's now. Mint is a secure service where you plug in your info from your different bank accounts, credit cards, student loans, and other financial accounts, and it keeps it all on track for you. In one place, you can see how much you're spending in total in certain areas (e.g. going to the bars too much, like I do). It also helps you set plans for paying bills and paying off loans. I've been using it for a couple years now, and it's a really handy thing to have around!

2. Khan Academy

Now I know what you're thinking: "Why the hell would I want to take online courses after I just spent 4 (maybe more) years in school?" You're not wrong for thinking that, so this may be something for a little while down the road. But there will come a day when you'll realize, "Damn, I really need to brush up on math," or, "God, I need to learn Python for my job," or, "I honestly don't know anything about literature." At Khan Academy, knowledge is free. Anything you want to learn on this website, you can do it all at no cost.

3. Rabbit

A lot of us, once we hit the real world, will be moving to new cities for our jobs. It's tough being in a new place with no one you know, so it's nice sometimes to hang out with old friends. Rabbit makes spending time together - even over distance - a lot easier. I've been in a long-distance relationship all through college, and it was always tough to have a night in together. We'd try to watch movies on Netflix together, and we'd have to coordinate through Skype and press play at the very same time, or one of us would have the other share their screen and we'd listen through really crappy audio from the other side of the call. Rabbit makes it all so much easier. Have your friend, family member, or significant other make an account on it (it's free), and then add each other as friends. One of you will set up a "room," where you can both watch the same YouTube video or Netflix movie on your own screens, but still have an open link to each other. My fiancée and I can attest, it's so much more convenient. Disclaimer: if you have really slow internet connection, this may not work the best, but even despite shitty university dorm wi-fi, I was able to get through a full documentary with my fiancée.

4. Finance courses from AOL.com

I can't stress enough how important it is being financially literate at this age. Coming from a background where finances were tough because we didn't know how it all worked, I believe knowing how to handle money is crucial to setting up a secure and successful life when we become adults. The finance courses at AOL.com are free to take and help you get a basic understanding for how to handle all this stuff. I attended a financial literacy workshop, and this was recommended as a great - and affordable - way to learn to make our way through managing our cash. Let's be honest, they really didn't teach us any of this stuff in high school.

5. Documentary Heaven

Okay, this might just be nerdy me talking, y'know, the guy who really enjoys learning. But documentaries are the best things ever, and you can find them for free at Documentary Heaven.

6. Jefit

Gym memberships of course cost a little money, but whether you have one or you don't Jefit makes it easy to track your fitness. I'm the sort of guy who loves to measure progress, and Jefit makes visualizing your body's progress simple. Whether you're working out in a gym or just heading out for a run and doing some push-ups, with Jefit, you can input all your metrics for your exercise session (time, reps, sets, pounds, etc.). You can also log your body measurements and watch their progress over time through charts the app creates - there are few things more satisfying than that sort of data. Jefit is available for free for both Android and iPhone.

7. RetailMeNot

Spending money sucks. When you have to spend it, why not try seeing if you can spend a little less? RetailMeNot is a source of thousands of coupons for just about any store or service available. This isn't going to change your life or anything, but it doesn't need any additional explanation when I say saving a few dollars here and there definitely helps you in the long run.

8. bevRAGE

BevRAGE is a nifty little app that can be really helpful for the 21+ folks out there. When you register on this app, you get offers for cash back on all sorts of drinks, whether you buy them at the bar, at a restaurant, or at the store. When you buy a drink that's covered under the different deals they offer, just take a picture of your receipt, and the app will send cash either to your PayPal, bank account, or wherever else you choose. It's available for both Android and iPhone. Be aware, though, there are some states or localities that might not allow it. I'm from Pennsylvania, and our alcohol laws are dumb, so I usually have to use this just when I'm visiting my fiancée in Maryland. But as long as you're not in a state with alcohol laws from 1796, you're all good!

9. Zocdoc

I don't think it's any secret that healthcare can really suck for millennials like us. Fortunately, Zocdoc can help. Zocdoc is a website and app that helps streamline the process for finding a medical professional that works for you. Here's how it works: you go in, select the professional you need to see (doctor, dentist, optometrist, psychiatrist, dermatologist, etc.), punch in your location and insurance provider, and it will find the best healthcare professionals for the easiest price. No need to call in to an office or even fill out paperwork in a waiting room - you can do all that through the app! Let me tell you, this is a godsend for an introvert trying to find healthcare.

Heading out into the real world can be a sucky transition, and it's easy to feel daunted. But don't worry, there are resources out there that can help you through it. This definitely isn't all of them - keep your eye out for more, because new ones are always cropping up! Hang in there, y'all, we'll make it as adults one way or another.
