Work harder on yourself than you do on your job....

Whatever good things we build end up building us.

You must take personal responsibility. You cannot change the circumstances, the seasons, or the wind, but you can change yourself. That is something you have charge of.

If you don't like how things are, change it! You're not a tree.

Youth is the gift of nature, but age is a work of art.

It is utterly false and cruelly arbitrary to put all the play and learning into childhood, all the work into middle age, and all the regrets into old age.

Old age is not a matter for sorrow. It is matter for thanks if we have left our work done behind us.

Have regular hours for work and play make each day both useful and pleasant, and prove that you understand the worth of time by employing it well. Then youth will be delightful, old age will bring few regrets, and life will become a beautiful success.
