You've changed my view on this subject, numbing might after all be the easy way out.
While I don't fully understand the numbing process, I know taking away the numbness will take time. I really don't have that. I'm going to continue to what I'm doing until I succeed or crash and burn. I'd rather fix all this once I'm wealthy and established, I also have no problem betting on a fluke to get there. This approach has gotten me closer to what I want faster than anything before.
When I see something, when I feel a genuine desire to have it there's nothing that's ever held me back. Usually, the biggest obstacle ends up being myself, other's don't stand a chance. Time after time I've failed, but only to get back up and claim what was mine.
Indomitable will is what lead Khan to expand Mongolia, Hitler to reclaim the Sudetenland, Napoleon to rise into power, Stalin to reign Russia, Ghandi to free his people, Caesar to establish an empire, Bismark to better his lands, Alexander to victory and Washington to freedom from tyranny. While I doubt I'll ever leave a mark as equivalent, i can only imagine they felt the same fire urging them towards success and glory.
