Thomas Edison said "If we did all the things we are capable of doing, we would literally astonish ourselves."
And I totally agree.
Have you ever had one of those days where you are unstoppable? A morning perhaps where you have a laundry list of chores and errands to do and you time it all to perfection, work like an efficient army ant and have it all finished in time for an early lunch?
Imagine working at that rate all the time. The things you could accomplish. I know that when I'm keeping busy and working hard I definitely sleep better at night. After all, what you do is who you are. I think John Ruskin puts it best when he says "What we think, or what we know, or what we believe is, in the end, of little consequence. The only consequence is what we do."
Whether it's your own blog, your own artistic project, your work, hobby, whatever- do something.
Eleanor Roosevelt said "You must do things you cannot do."
Try that, when it fails, try again, fail again. Fail better.
Just make sure you don't fail to act- because in the end- that is the only real failure there is.
