Time is a limited resource. When it comes to your time, the rules of supply and demand break down.
In theory, more demand for your goods, services, time, should always be a good thing. It's nice to be in demand. But time is the one thing you can't create more supply of.
So structure your world so that every time more demands are made, you can address them with confidence. Maybe this means reveling in the joy of picking the things that are most important to you. Maybe it means learning to delegate. Maybe it means learning to charge more for what you do.
Don't let anyone tell you your time isn't the most precious resource you control.
