Though our conduct seems so very different from that of the higher animals, the primary instincts are much alike in them and in us.
Hard work is the key to success, so work diligently on any project you undertake. If you truly want to be successful, be prepared to give up your leisure time and work past 5 PM and on weekends. Also, have faith in yourself. If you come up with a new idea that you believe in, don't allow other people to discourage you from pursuing it.
Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to the end, requires some of the same courage which a soldier needs.
O friend, my bosom said,Through thee alone the sky is arched.Through thee the rose is red;All things through thee take nobler form,And look beyond the earth,The mill-round of our fate appearsA sun-path in thy worth.Me too thy nobleness has taughtTo master my despair;The fountains of my hidden lifeAre through thy friendship fair.
