#264-1. God gives every bird its worm, but he does not throw it into the nest.
#264-2. Action is a great restorer and builder of confidence. Inaction is not only the result, but the cause, of fear. Perhaps the action you take will be successful; perhaps different action or adjustments will have to follow. But any action is better than no action at all.
-Norman Vincent Peale
#264-3. Right actions for the future are the best apologies for wrong ones in the past.
Sometimes it seems like a worm was thrown into our nest (lucky day feeling) or someone else's (much more often) but I believe sincere effort and fruits even out in the medium-to-long term, and it is we who do not make the connections easily. The process changes the person, even if the effort superficially appears to yield no result.
Any action is better than inaction caused by too much pondering. It is good to remember this when trying to begin something. However...
The keyword in the third quote is "right"—plunging into activity that repeats past mistakes and justifying it with "any action is better than no action" will harm, not help.
