An interesting video about foreigners in Thailand. However, it speaks to a broader condition of the Western Martial Artist.
Remember, learning Muaythai in the west is both accelerated and decelerated. It isn't possible for 90 percent of martial arts enthusiasts in the West to train like a Thai fighter (2x a day, 6 days a week, and fighting as early as under 10 years old).
Everyone has to focus much harder on fundamentals and proper technique, in order to make up for the years that thai kids spend perfecting the kind of balance and coordination they perform with. You do, however, have the advantage of learning certain tricks and having certain training resources available to you before you ever have to fight, if at all (which most Thai fighters pretty much do not).
So, you may not be that guy in Thailand getting schooled, but remember: every step you take here has to be gradual, and your best friend in training is consistency.
