Moving out, working a generic cashiers job was a slap in the face. When I realized just how sheltered and oblivious I've been my entire life, I started working hard. I was managing( doing the bosses job) 4 different stores after a few months; Because I was responsible for thousands of dollars each day, I quickly developed a strong Te(my F is now 11%).
When I made the decision to go back to college; I RARELY go out to parties, no matter how close they are. Usually I'll make an hour appearance so people don't bitch about me being anti-social. LOL
I spend most of my time studying, or entertaining myself. After a long time of trying to figure out who you are, what you want, and what is important to you, I think you will find the perfect balance to suit YOU tater.
That might mean you might party a little more than you study, but it is about you being happy and content with who you finally choose to become. A happy person is a healthy person; I believe once you find yourself, you will begin to make the correct, life-improving decisions you are searching for.
I think association with people does effect what decisions people make, however, your independence and the ultimate outcome rest in your hand. You have to be able to say no, and not let people persuade you into doing something you think might effect your self-growth. It is hard when you are at a young age, but after a while, even if it upsets people, at least you are doing the right thing for yourself. : )
Half of my friends are party animals, and the other half are like me. No matter what they ask me to do , or how they try to persuade me, I do what I think is right for me to do.
