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 manage 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 faintest.

I am not machine, thought I work with the precision of a machine and the intelligence of a person. You may 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.
