Do what’s best for you. Never let anyone determine what you should do- especially if it will tarnish your image or prevent you from reaching your destiny.

Just say “no” and don’t expect them to understand.
It’s not being selfish it’s looking out for #1
You must take care of yourself before you can help anyone else!

Never remain in an unfulfilled relationship because you are afraid of breaking someone’s heart. Your happiness is far more important.
