employment, but there have been many great men who did not know what
they were fitted to do until accident or necessity gave them an
opportunity.

Success means simply concentration and perseverance.

Whether you decide to be a mechanic, a lawyer, a doctor, or a merchant,
the one thing to do is to fix all your mental powers upon the goal you
select, and then call all the forces from within and from without, to
aid you to reach it.

It would, of course, be folly for you to select a profession which
requires special talent. No matter how you might concentrate and apply
yourself, you could never be a great poet, a great artist, or a great
musician.

You have not the creative genius.

But law, medicine, mechanics, or mercantile matters, with your good
brain and fair education, you could conquer.

You say you vacillate from one to another, like the wind which goes to
the four points of the compass in twenty-four hours.

But you are very young, and this should not discourage you.

It would be well to think the four vocations over quietly, when alone,
and sit down by yourself early in the morning asking for guidance. Then,
when you feel you have made a decision, let nothing turn you from it.
