I always remind myself that Paul Gauguin started painting for the first time at 35, and almost at 40 decided to stop being a wealthy stock broker to live as a painter. Regardless of the ethics of that decision (he did leave everyone in his family behind, after all) I do think it's pretty impressive that he picked up a profession like that so late and developed it in such an impressive way (I love his artwork, I think it's incredibly beautiful).
