Where did I say that I'm giving advice? The poster asked the question "did you wait until you got to Thailand" and my answer was yes I did. People can choose to do it any way they want specific to their situation.
Lol...daunting? The time it took me to get accustomed to retirement was about 30 seconds! I do agree with you 100%... I keep my expat friends circle pretty small and tight.

I prefer to meet up with Thai people (females!) and learn more about the country.
