Men who reach decisions promptly usually have the capacity to move with definiteness of purpose in other circumstances.
Andrew CarnegieThe average person puts only 25% of his energy and ability into his work. The world takes off its hat to those who put in more than 50% of their capacity, and stands on its head for those few and far between souls who devote 100%.
Andrew CarnegieThe first thing to do about an obstacle is simply to stand up to it and not complain about it or whine under it but forthrightly attack it. Stand up to your obstacles and do something about them. You will find that they haven't half the strength you think they have. Just stand up to it, that's all, and don't give way under it, and it will finally break. You will break it. Something has to break and it won't be you, it will be the obstacle.
