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 can never be safe; I always try and go against the grain. As soon as I accomplish one thing, I just set a higher goal. That's how I've gotten to where I am.
