An old friend once taught me that if you don’t stand 4 something you’ll fall for anything. When you stand 4 something it means saying no 2 the things you don’t.
If you spend your time fulfilling the request of others, you’ll find yourself doing a lot of wheel spinning, and not getting where you really want 2B. Spend some time learning 2 say no. In fact make no your default answer so that you can generously give in an area that matters 2U.
