Foolishness
What seems like a liability to most people can also be a great asset.
Our learned behaviors, or experiences, are often what hold us back from achieving our goals and dreams. It is due to experience that we hesitate, and a lot of times it's for good reason. But experience is the type of thing that can back-fire, and make you miss your window of opportunity.
Over the years, I have had hundreds of ideas about different products and services. Unfortunately though, my past failures had an adverse effect on my willingness to follow through. I am not 100% timid, heck, not even 50%, but my lack of desire to be foolish enough to do what I think needs to be done is a bit disheartening. Of course, I am my own worst critic. A lot of what I have accomplished in my life came at times when I was most daring, risk-taking, and foolish. I will take foolishness over jadedness any day of the week.
If you live each day as if it's your last, someday you'll most certainly be right.
