I would like to explore this challenge in a little depth to try to show those who wish to start on this language adventure that although one may not reach the peak, and become fluent - many don't, that at least one can pause at different vantage points up the mountain, enjoy the view and at least converse with your fellow adventurers even if the locals don't seem to understand a word you utter. That question has been tossesd at me often. As a student of Thai my ears are finely tuned to the nuances of tone. It is the tone of this question which is often more interesting than the question itself. Tones that range from bewilderment to complete incredulity, admiration to simply derision.
Motivation however is paramount.
Defining, quantifying sorting out the real reason for studying this exquisite oriental language and then admitting it. If not to others then at least to oneself. Once you have settled on the main reason then you are well ensconced at base camp. The view to the top of the mountain is pretty clear. The answer is obvious.
