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.
We speculate as to what is in store for us. But we not only undergo events, we in part cause them or at least influence their course. We have not only to study them but to act.
