"A lot of people will try to talk you out of pursuing your dream. The world has too many people who are happy to discuss why something might not work and too few who will cheer you on and say 'I'm there for you'.
The more time you spend navel-gazing, the longer you give those negative gravitational forces to keep you in their tether. If there is something out there that you want to do.. don't focus on the obstacles. Don't ask permission. Just dive in."
