Fuck what they think. Just go be happy.

Let nothing get in the way of your happiness.

Anything or anyone that impedes the successful ventures you have in mind for your life are in need of swift removal from your life. Ultimately you are going to have to find yourself needing to make a change in your life and sometimes that change is going to be people and most likely they won't understand your reasoning behind the sudden change but honestly who cares whether they do or not? Some people in life will probably see this as being selfish, but I think it is way more selfish to literally not support or even get in the way of someone who wants to reach for something they believe in.

Never feel guilty for wanting to be successful and happy on whatever path you decide to take in life.
