If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
I was working in corporate Canada and I was doing all right. But I was burnt out... Long hours, a lot of clients. I just wanted to get away. Track and field was sort of like the elimination thing. I just wanted to go and do something. Exercise my brain and my body and kind of gravitate to that.
