I work at the YMCA in my small town, and just a few days ago I also started roofing. The benefits are already very noticeable to me, and likely to anyone else who also works two or more jobs over the summer while on break from school. My roommate is working three jobs, but I suppose I'm not as ambitious as him, only working two. Here are a few reasons why you should take on multiple summer jobs.
6. It'll Keep You Busy
You can normally find something to do over the summer: reading, playing video-games, binge-watching Netflix, walking the dog, working a little, etc. After a while this gets old, and you're ready to go back to school so that at least you'll have something to do. With two jobs, you'll barely have time to do those other things, so they'll stay fun for longer!
5. Your Jobs Can Complement Each Other
To take myself as an example, I work all morning (about 6 a.m. to noon) up on a roof, pulling off shingles, throwing them away and putting new ones on, and then I go home, shower, eat lunch and come work at the YMCA where there's nice air conditioning and no roof I have to climb around.
4. Your Job Could Involve Eating Food
If you work in a restaurant, then you may get free food on your break or free drinks while you're working, which means you're spending less money on food/drinks while simultaneously making more money! Win-Win!
3. You Can Work Different Kinds Of Jobs At Different Times
For example, you could be a waiter/waitress on the weekends (when restaurants are busier so you'd make more tip money) and then another minimum wage (or higher!) job during the week. This wouldn't allow for weekends off, but the money would be pouring in.
2. You Have Lots Of Options
You could mix and match some of the things I listed above, or do something entirely different that would maximize your income stream.
1. Money
Obviously the underlying theme here is making more money. With two jobs you will make a lot more money than you will with one (obviously), but depending on what you do and how you do it the difference could be extreme. I've already made a lot more money working a second job than I did with just one. I strongly encourage it for anyone struggling to buy their textbooks, buy their food, that needs a new car or computer, wants more money, or anyone who doesn't have anything better to do! Everyone needs money, and working two jobs is a good way to do it.
