No matter how close the blood tie between two beings, even twins, each soul comes into the world alone, and with a separate life destiny to work out.
If I have worked out my destiny to financial independence, that does not entitle you to a share of it. If it seems best for me to aid you, it is not because a blood tie makes it a duty. I grow to believe there is a sort of curse on money which is not earned, even when it is bestowed by father, on son or daughter.
It cripples individual development. Only when money is earned is it blest.
Regarding your future profession, I cannot agree with your idea that because you feel no particular love for any one calling, and have a halfway tendency toward several, that you will never be a success. Great geniuses are often consumed with a passion for some one line of study or 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.
