A number of years ago while trying to work full-time, be the room mom, the scout leader, stuff the classroom folders, and a million other things one of my mentors shared this with me:

The mother who gives up her life for her children does them no kindness but rather burdens them with the legacy of a life unlived. --Janet Falldron

I still struggle with taking time away from my kids (13, 11, and 9) to ride and do other things, but I don't want them to ever think THEY prevented me from following my dreams - what guilt! And as much as they whine about it, they still like it when their friends say, "Your mom rode how many miles? OMG! No way."

Way.
