Personal choices outperform technology choices

This dinger at the end of Mattt’s WWDC wrap-up is everything:

Taking care of yourself — sleeping enough, eating right, exercising regularly — will do more to improve your productivity than any language or framework out there. Your ability to communicate and collaborate with others will always be a better predictor of success than your choice of technology stack. Your relationships with others are the most significant factors of success and happiness in life.
