There comes a point where adding more does not improve things. Another tool. Another course. Another idea. At some point, more just becomes weight.
Knowing when you have enough; enough information, enough direction, enough to begin; is a quiet form of wisdom. It allows you to shift from gathering to doing. From preparing to progressing.
Clarity does not always come from more input. Often, it comes from deciding that what you have is already sufficient to take the next step.
