A Perfect Time And I missed It

When I was young and strong I felt there was nothing I couldn't do, but I found there were things I didn't know how to do and it made me angry. Now that I am older there are few things I don't know how to do, but I can't do them all because I no longer have the strength and It makes me angry. Somewhere between the two there must have been a perfect time but I was busy and missed it!
