First, an admission:
I am not a great fan of quotes being distributed via tweets/ facebook and blogs. If I needed inspiration from a one-liner or felt the urgent need to overdose on saccharine, I'd go and Google something to cheer me up.
(One of the reasons I abandoned Facebook is because I could not take another eCard post.)
The reason why I make an exception - and even if you have low tolerance for aphorism like I do - then please bear with me on this one.
I discovered this quote in the footer of a blog. It has been awhile since a quote has resonated with me so much. (The source - as far as I can gather is as indicated in the image.)
