And one other thing it is your life not anyone else's. Choose the things that make you happy not what people want you to have.
Surround yourself with people that truly love you and care about you and want to see you do well in life, and not fakers, haters and liars. Or people that just use you for what you are or what you have.
Always be able to look yourself in the mirror every morning and be all right with yourself. Be true to yourself.
Be optimistic and have a good outlook on life but do not be delusional.
Each and every time you are wronged, learn from it, don't let it change you, but cover your ass a little better because the next time will surely come again I promise.
