Guess what I am…

“I am you constant companion. I am your greatest helper and heaviest burden. I will push you onward and upward or drag you down to failure.  I am completely at your command.  Ninety percent of the things you do might just as well be turned over to me, and I will be able to do them quickly and correctly.  I am easily managed, show me exactly how you want something done and after a few lessons I will do them automatically.  I am the servant of all great people and, alas! of all failures as well.  I am not a machine, though I work with all the precision of a machine, plus the intelligence of a man.  You can run me for profit or run me for ruin – it makes no difference to me. Take me, train me, be firm with me, and I will place the world at your feet.  Be easy with me and I will destroy you.  Who am I? I am Habit.” _Author unknown
