You can’t possibly give of yourself to everyone. So play to the strong (those who are ready and able to make use of what you have to offer), not the weak (those who seem to need what you offer, but aren’t really ready to accept what you can do for them or make good use of it). By doing so, you’ll grow faster, and you’ll attract more of what and who you desire and less of who/what are a waste of your time and energy.
