It's nice to ask for advice, sure. But don't let other people dictate what you can and can't do with your own life. It's your life, not theirs. Here is a list of things you are in control of, and you shouldn't let anyone convince you otherwise:
Your major.
It's your degree, not theirs.
Your career.
You decide what job(s) you want to have.
The things you say.
Speak up for what you believe in and don't let others try to silence you.
The things you do.
Do what makes you happy.
What you choose to wear.
Wear whatever you want, whenever you want. So what if your friend hates those shoes? It's not up to her.
What you choose to eat.
Eat that extra cookie if you so desire. Or don't. Eat whatever you want.
Coping mechanisms.
If you want to curl up in a blanket and watch Netflix all day, do it! If you prefer going out, that's fine! Nobody dictates how you deal with stress and other issues except for you.
Who you are as a person.
Never let anyone else try to tell you who you can and can't be. Cut them off if they try to make you feel bad about how you are or the things you do because, yes, you have control over doing that too.
Don't let a single person try to tell you that you can't do these things or try to make you feel bad for living your life the way you want to. Live your life to the fullest, it is your life!
