Start now. Live for yourself. Do what you want to do.
Life is too short to not live for yourself first. Your friends, family and cohorts may or may not accept your the life you want to lead, but doing so is what you must do if you want to be happy or, in other words, if you try to align your happiness with the pleasing of others, you will rarely find a way to make that work.
Of course, some people won’t understand your choices. They might not want to get them because your choices might offend them or there may be jealousy in them. But such is life. You can’t please everybody. When you follow your heart, you will actively displease them. They’ll be just fine. They are too worried about themselves to worry about you for too long so just let it go and accept it as par for the course.
Ask yourself: Are you living for others because they think they know what will bring you happiness?
Life is completely what you make it. Your perception is what you decide it is. You have the power to see life through a certain lens. If you don’t like what you see, make changes until you do like what you see.
Create life for yourself that is a reflection of what makes you happy and fulfills you.
