Habit

Found this interesting poem from a book I am currently reading. Would like to share it with you:

Habit

I am your constant companion.

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 will be able to do them 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 men

and, alas, of all great failures.

Those who are great, I have made great.

Those of you who are failures, I have made them failures.

I am not a machine, though I work with all the precision of a machine.

plus the intelligence of a man.

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 put the world at your feet.

Be easy with me, and I will destroy you.

Who am I?

I am HABIT!
