The bar for yes should be high and continuously get higher

The bar for yes should be high and continuously get higher. When you’re first starting you might say yes to everything to get experience. Later, however, you’ll need to be more selective. Most people end up saying yes to mediocre opportunities. Anyone can say no to crappy opportunities. Only a master will say no to good opportunities. If you don’t say no to good opportunities, you’ll never have the time to pursue great opportunities. But if you don’t say no to good opportunities you will never have time for great ones.
