You shared your favorite quotes with me on this blog (thanks for all!) and I find, like you, that I go back to the same words/inspirational thoughts time and time again whenever I feel I need a little something new. (particularly when I'm injured and frustrated!). But I also think a good perspective is important too - so here is another one to share:
"Life isn't about finding yourself. Life is about creating yourself."
It makes me feel tremendously excited about the potential that lies in anything new - do you have any opportunity where you have to get out of your comfort zone and stretch a little? Scary, but exciting, yes?
