I am your consent companion.  I am your greatest helper or heaviest burden.  I will push you onward or drag you down to failure.  I am completely at your command.

Half of the things you do you might as well turn over to me and I will do them-quickly and correctly.

I am easily managed-you must be firm with me.  Show me exactly how you want something done and after a few lessons, I will do it automatically.

I am the servant of great people, and alas, of all failures as well.  Those who are great, I have made great.  Those who are failures, I have made failures.

I am not a machine though I work with the precision of a machine plus the intelligence of a person.

You may 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.
