It is man's own fault, it is from want of use, if his mind grows torpid in old age.
The man who succeeds above his fellows is the one who early in life, clearly discerns his object, and towards that object habitually directs his powers. Even genius itself is but fine observation strengthened by fixity of purpose. Every man who observes vigilantly and resolves steadfastly grows unconsciously into genius.
Do not let yourselves be discouraged or embittered by the smallness of the success you are likely to achieve in trying to make life better. You certainly would not be able, in a single generation, to create an earthly paradise. Who could expect that? But, if you make life ever so little better, you will have done splendidly, and your lives will have been worthwhile.
