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 think we are living in selfish times. I'm the first one to say that I'm the most selfish. We live in the so-called 'first world,' and we may be first in a lot of things like technology, but we are behind in empathy.
