I like to think everybody has a chance to be who they want to be.
While I do enjoy working in the corporate world while eating and training like an athlete - admittedly at times it is a divine juggling act. Sometimes it is as coordinated as the ballet and other times like trying to carry water in a sieve.
It can be a struggle, but that's fine, I accept that.
I think a lot of people get sold the idea that mixing two polar opposite goals is easy. "You CAN do this"! (I want to be a marine biologist, I can, but I don't want to struggle with the after work assignments.)
So the question I think we need to ask ourselves is not what would make you happy? But, what are you willing to struggle for? Because happiness requires struggle.
