In order to write novels for a living - it's not pathological, but I do think and worry and brood and fidget about stuff that I'm working on.
Everyone I know who used to be in the intelligence community is moving into the corporate world.
In my life I've learned that true happiness comes from giving. Helping others along the way makes you evaluate who you are. I think that love is what we're all searching for. I haven't come across anyone who didn't become a better person through love.
