Do a little bit more than average and from that point on our progress multiplies itself out of all proportion to the effort put in.
Mistakes are merely steps up the ladder.
Enter every activity without giving mental recognition to the possibility of defeat. Concentrate on your strengths, instead of your weaknesses... on your powers, instead of your problems.
Determine what specific goal you want to achieve. Then dedicate yourself to its attainment with unswerving singleness of purpose, the trenchant zeal of a crusader.
