Starting to fail

Two things happened to me this month: I missed a meeting and I missed a train.
That had never happened to me in 20 years, and for most people, it would probably just be another anecdote. But I feel there may be something else. I may be hitting my ceiling.
I’ve been feeling for several months now that I’m trying to swallow more than I should. It has worked so far. I see how these two examples may seem pretty small, but I think they were a good warning: stop and delegate before it’s too late.
