How wrong can you be.
Yes I do have a wife but no children. My wife runs her own business and could easily support me but I do not want, or ask her, to do that.
I eat at restaurants most days because I prefer doing that to spending time buying ingredients, cooking them and cleaning up afterwards. I eat whatever I want and most days that is not 40 Baht soup; but sometimes it is.
The house is paid for as are the three cars. The farm generates a healthy income. I spend about 20% of my income from abroad each month and the rest is poured into more savings and investments.
I readily admit to being careful with my cash. Mostly because I remember how damn hard it was to earn it.
My only real reservation in respect of the OP is about the wisdom of making the leap at his age. Other than that if he has the determination to make a success of it go for it. I don't think there is any need for him to torch his assets back home. That would be unwise. The income would be enough.
