If you've got an idea, start today. There's no better time than now to get going. That doesn't mean quit your job and jump into your idea 100% from day one, but there's always small progress that can be made to start the movement.
Every photo you take communicates something about a moment in time - a brief slice of time of where you were, who you were with, and what you were doing.
I actually think some of my best moments in life have been while I was with people from Instagram - whether it's super late nights getting a release out or being able to travel to places I'd never visited and meeting some of the most interesting people I've ever met.
I grew up as a photo nut. Every Christmas I would get a new camera. It's a huge part of my life.
When people say that college isn't worthwhile and paying all this money isn't worthwhile, I really disagree. I think those experiences and those classes that may not necessarily seem applicable in the moment end up coming back to you time and time again.
