You might not realize it, but when you're filling out your planner it suddenly hits. Every day is filled with either assignments, events, work, appointments and more. Did you mark a day on your planner that is dedicated to just you? Don't forget you have yourself to take care of.
Doing "too much" can be a good thing. You're getting more than enough units out the way, you're making money at work and you're involved on campus. What could possibly be wrong with that?
Once you end up getting caught up in such a busy lifestyle you'll forget to care for the most important person - you. You're putting more stress on yourself than you can handle and your happiness is suffering. Is it worth becoming so stressed out that you start to beat yourself up about it?
You took one too many units just so you can graduate on time. Why does it matter? It doesn't matter how fast it takes you to get a degree, it just matters that you get it. Whether it be this year or next year.
You'll get upset that you didn't have enough time to complete a homework assignment. You didn't want to tell your boss, "No, I can't stay later," because you don't want to disappoint him. You're a good, reliable employee. You wouldn't want him to think otherwise.
You don't have time for your friends anymore. Your schedule is too complicated to make plans with them. Don't you miss spending time with them? I'm sure spending time with them would take some stress off your shoulders.
If you keep doing "too much" you will get a lot done. Your resume will look better than it ever did and you will have more than enough experience. But did you have fun along the way? Did you create college memories that you will cherish for the rest of your life?
Maybe you could do both, but if you're like me, you might get lost in the midst of it all. Take a breather and don't be so hard on yourself. Work less, take your time in school and have fun. If you can't dedicate a day to yourself at least once a week, you might want to make some changes!
