How often do you start something without any homework?
Yet preparation is usually all that's within our control. We waste countless hours by ignoring it. Whatever the project, think ahead: consider its needs, its problems, its shortcuts. Give yourself every advantage. Build your confidence, create options. Time spent doing this will be handsomely rewarded.
