If you're going to succeed, you need a vision, one that's affordable, practical, and fills a customer need. Then, go for it. Don't worry too much about the details. Don't second-guess your creativity. Avoid overanalyzing the new project's potential. Most importantly, don't strategize about the long term too much.

There is no man more pusillanimous than I when I am planning a campaign. I purposely exaggerate all the dangers and all the calamities that the circumstances make possible. I am in a thoroughly painful state of agitation. This does not keep me from looking quite serene in front of my entourage; I am like an unmarried girl laboring with child. Once I have made up my mind, everything is forgotten except what leads to success.

Nothing is more important in war than unity in command. When, therefore, you are carrying on hostilities against a single power only, you should have but one army acting on one line and led by one commander.

Hard knocks have a place and value, but hard thinking goes farther in less time.
