Striving is fine, as long as it’s tempered by the realization that, in an entropic universe, the final outcome is out of your control. … When you are wisely ambitious, you do everything you can to succeed, but you are not attached to the outcome—so that if you fail, you will be maximally resilient, able to get up, dust yourself off, and get back in the fray.
