Right now in my life I'm being challenged.  Not in the negative way we often think of life's challenges, but in a positive way.  I'm being given opportunities that I hadn't sought out.  I'm being asked to do things that are outside my comfort zone.  My usual reaction would be to say no and suggest someone else, but I'm being challenged, but my mentor, by my friends, and by my loved ones to step up and give it a go.  Scare though it is I'm taking the Mark Twain approach.  I don't want to look back in 20 years and wish I'd said yes, so I'll say yes now.  I will risk failure.  I will challenge my fear.  And I'll give it a bloody good go!
