WHO AM I?

I am your constant 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 the things you do you might just as

well turn them over to me and I will be able to do

then quickly and correctly.

I am easily managed - you must merely

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 all great individuals 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 all the precision of a machine plus

 the intelligence of a human. You may run

me for a profit or run me for a 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.
