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.
“Some people say my work is often depressing and pessimistic, with the emphasis on death, blood, overcrowding, strange beings and so on, but I don't really think it is.”
“Plan for this world as if you expect to live forever; but plan for the hereafter as if you expect to die tomorrow.”
