Who am I? I am Habit!

Your best friend or greatest enemy, I am your greatest comparison. I am your greatest helper or your heaviest burden. I will push you onward or drag you down to failure. I am completely at your command. Half the things you do, you might as well turn over to me and I’ll do them quickly and correctly. I’m easily managed, but you must be firm with me. Show me exactly how you want something to be done and, after a few lessons, I’ll do it automatically.

I’m the servant of all great men and, alas, of all failures as well. Those who are great, I have made them great. Those who are failures, I have made them failures. I work with the precision of a scientist and the passion of a patriot. Take me, train me, be firm with me and I will put the world at your feet. But be easy with me and I’ll destroy you.

Who am I? I am Habit!
