Nurture your mind with great thoughts, for you will never go any higher than you think.
Argue for your limitations, and sure enough, they are yours. People are always blaming their circumstances for what they are. I do not believe in circumstances. The people who get on in this world are the people who get up and look for the circumstances they want, and, if they cannot find them, make them. In times of stress, be bold and valiant. Quit now, you will never make it. If you disregard this advice, you will be halfway there. Imagine you only have one year to live.
To think is easy. To act is difficult. To act as one thinks is the most difficult of all. Until you try, you do not know what you cannot do. All who seek the roots of life dig in solitude for them. It is by what we ourselves have done, and not by what others have done for us, that we shall be remembered in after ages. The man who is waiting for something to turn up might start on his shirt sleeves. Begin difficult things while they are easy. A thousand-mile journey begins with one step. Stop freewheeling, get into gear, and do something with your life. There are so many avenues to explore, so why not explore them? Never be afraid to step into the unknown, into the new.
Do not play for safety; it is the most dangerous thing in the world. If you cannot do great things, do small things in a great way. Believing is one thing, doing another. Many talk like the sea but their lives are stagnant marshes. Others raise their heads above the mountain tops, while their souls cling to the dark walls of caves Whoever I am and whatever I am doing, some kind excellence is within my reach. Better get a stiff neck from aiming too high than a hunch from aiming too low.
