A friend posted this quote from October's "Runner's World" on his blog and it inspired me...
"There will come a day when I cannot do this. Today is not that day!"
So get out there and run or bike or serve or fight cancer or whatever you do! You can't find a better day than today to keep going or get started. Go, go, go!
(I rode 7.5 miles into a strong north wind today. My average on the way out was 13.8mph. I turned around and sprinted home ending with a 17.5mph average. There will come a day when I can't do that. Today was not that day.)
