Don't sugar coat it... How was it really?
Edit: To the OP, I'd suggest spending some time in Thailand, find some businesses that interest you and talk to the foreign owners to see how they did it, what challenges they face, etc. Then ask yourself if you have the skills and the grit and determination they do. I've got my eye out for a future retirement situation, not so much to make money, but to give me something to do that won't drain me.
