I recommend to read Theodore Roosevelt's Speech. Paris, France, April 23, 1910. Many US higher education institutions recommend their students to know it:

"Our sympathies do not belong to the skeptic, who again and again calculates the options; not the one who tells us where the hero stumbled, or tells where the leader could have done better. Our faith and praise rises to those who are really at the center of events, whose face is disfigured by dirt, then blood; Who bravely fights and really suffers; who, mistaking, over and over again overcomes the obstacles and approaches the truth; because there can be no attempts without errors and obstacles; But it is such a person who truly suffers for the sake of accomplishment; he has tremendous enthusiasm, zeal and the ability to sacrifice himself; he does not spare himself and spends his life on what is worth such effort; who, in case of victory, will receive the glory and honors of the highest achievements, and in case of defeat at least lose bravely and fearlessly, and his place will not be among those cold and timid souls who do not know either victories or defeats "

Push:
Great speech. Therefore, those who act are reaching great heights. And not those who follow those who act, or condemn and discuss those who act.
The one who carries a lantern stumbles more often than the one who follows. But only the carrier lantern knows where it goes, the others just follow the outgoing light.
Never run after the passing sun. Create your own energy source.
