A good reputation travels more comfortably when it does not outrun your capacity.

Being known as reliable brings more requests than being reliable can absorb. Word spreads faster than your available hours, so the very quality that earned the reputation starts to be eroded by the demand it created, and the first dropped ball is the one people remember. Managing what is expected of you is part of keeping the thing that made you worth recommending; saying no is how a good name stays true.

When the next request arrives on the strength of your reputation, check the calendar before the compliment. Decline early rather than delivering late.
