If you want to preach, you don't need a church.
If you want to write, you don't need a pen.
If you want to teach, you don't need a school.
If you want to sing, you don't need an accompanist.
If you want to dance, you don't need music.
If you want to paint, you don't need a canvas.
If you want to help, you don't need an emergency.
If you want to act, you don't need a stage.
If you want to invent, you don't need a laboratory.
If you want to heal, you don't need a hospital.
If you want to play, you don't need a sandbox.
The old structures that once bound innovation and opportunity to a particular time and place are fading away and nearly gone. The time and place, then, to do what you must is here and now. If you can dream it, you should do it.
