To think is easy. To act is difficult. To act as one thinks is the most difficult of all. Nurture your mind with great thoughts, for you will never go any higher than you think. All that is necessary for evil to triumph, is for good men to do nothing. Do not tell me this a difficult problem. If it were not difficult it would not be a problem. Energy and persistence conquer all things.
One cannot govern with buts. The winds and waves are always on the side of the ablest navigators. 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. Begin to be now what you will be hereafter. What lies before us and what lies beyond us is tiny compared to what lies within us. To avoid criticism, do nothing, say nothing, be nothing. If you do not do it excellently, do not do it at all. Because if it is not excellent, it will not be profitable or fun, and if you are not in business for fun or profit, what the hell are you doing there?
