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 over to me, and I will be able to do them quickly, 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 people; and alas, of all failures as well. 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 being.
You may run me for a profit or turn 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?
