I am guilty of this. Frequently. Fortunately, I often realize that I've lost touch with myself and that it is time to prioritize me for a while.
This doesn't mean hours and dollars getting massages and pedicures, though I thoroughly enjoy it and wish for it weekly. (click donate :) It means letting some things go, taking it easy and getting present with myself. Breathing deeply, thinking about the things that set my soul free in song. It means taking my time and putting a stop to multi-tasking; Sitting down to read with my children instead of trying to write an article while cooking dinner; Closing the computer and watching my kids play while sipping my coffee.
Take a few minutes every day to simply be with yourself. Be quiet. Be still. Just be.
