A very wise young lady gave me the best advice in my entire life, when I was in a particularly deep depression, something I've been repeating to myself for over 40 years. Every morning when I get out of bed and before any activity of the day: when I take a shower, when I do dishes, cooking the family meal, mowing the grass, etc., etc. It probably wouldn't match anybody else's notion of "inspirational", but it's helped me through some really bad times.

Get off your *** and do something useful.
