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 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 man.  You may run me for a 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 ease with me, and I will destroy you.

Who Am I?
