There will be plenty of people who will doubt you along the way. If not, then maybe they just don’t see where you’re headed. Not everyone is meant to understand what you have to do to step out and be great. Not everyone needs an explanation for your decisions.

Who else is going to be responsible for that, if even you aren’t willing to give yourself some credit?
