“I am your constant companion –
your greatest helper or heaviest burden.
I will push you onward or drag you down to failure.
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.
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 your habit.“
