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.
I am managed with care -- you must be firm with me. Show me exactly how you want something done, and after enough lessons, I will do it automatically.
I am the servant of all great people and, alas, of all failures.
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 and 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, and 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!
