Found this particularly interesting as I was using "not feeling ready" as an excuse not to start. I feel like with most people, they never quite feel ready enough to even start. Though readiness in these cases is usually just an excuse to procrastinate change and things that might be hard. I feel that for myself anyway.
Not only is this a message of starting before you feel ready, but appreciate the hustle as well! Renting a charter plane you can't afford and then go sell the tickets, that's ballsy!
