Failure is a funny thing.
From our very first day at school, we were taught that it was wrong to fail. I still remember the big red crosses on my school work, and how bad I felt when I didn't get the marks I expected too.
We're taught that failure is wrong - taking risks is dangerous - and for many of us, it becomes easier to 'stay safe' rather than putting ourselves out there and risk looking like an idiot.
The only problem is that if you REALLY want a life that you love, you're going to have to take risks to get there. And sure, you might fall, in fact, you probably will. Nothing good comes easy. But EVERY failure is a stepping stone to success - and eventually, you'll fly.
