Retiring in Thailand/Indonesia/Taiwan

Just hit 40 and started thinking (or re-thinking) about available options. Singapore is home but wonder if early retirement (say 50-55 no kids) is actually meaningful in Singapore - nothing much to do, high cost of living (still need a purpose).

Starting wondering if living less in SEA, keep two dogs and do a small business would work and looking for advice.

Threw Taiwan into the mix although harder to obtain an investment or retirement visa. Also more expensive.

Love to hear from those who made it and where are you and what are general financial considerations to live comfortably.

Broad question I know and more to hear stories than to pick advice that will make it work exactly for me.

Positive vibes!
