2. Make peace with the fact that there is NO FRESH AIR in the entire city of Bangkok. You dont need a mask. How will you enjoy the pungent, deeply layered odour of rat and damp city while wearing it??
3. Take time to meet the locals :) the little people if you will... They're super friendly and very relaxed.
5. Take a longboat ride in Krabi and see the best beaches in the world... dont let any drunk Germans sit next to you. They will think you're one of the local girls and try to touch your leg by pretending to wipe their brow with your towel! Horny german males visiting for the sex industry should be banned from Thailand.
