There's this little thing I say to myself and that I share with my creative friends. It's important - critically important to ask yourself this question in exactly this way about where you are in what you are doing.
"Am I in striking distance of doing the best work of my life?"
Of course we want to do the best work of our life every day. It's just not sustainable. But are we environmentally setup with our team, our learning, the fluid dynamics of multi brain collaboration to be able to say we are in striking distance of doing our best work??
If the answer is no. You gotta go. Go fast.
