The difference between wanting to become something and being something is doing it.
And once you start doing, and if you are really passionate, (or if you have a really big deadline and you are really passionate), you will eventually work up a sweat.
Exercise and athletics are not the only ways to sweat. You can work up a sweat with your creativity.
So, go ahead and work yourself up into a creative lather. Aspire to perspire. Flex your elbow grease. Stew in your own…creating.
Turn off the distractions and turn on the sweat. And then sweat it out.
And then come back and tell us about what you did in the comments.
