I've trained for the past 8 years, initially in a blend of TKD, Krav Maga, Kenpo and Muay Thai. For the past two years I've trained Muay Thai. I consider my training pure play. I think a huge component is your mindset, to me it's a passion and a joy hence play. Now I'm sure there will be a few quips going into the physiological aspects blahfrickenblah. To me, it's fun, it's play !
Good luck, hopefully you'll be able to find another dojo and begin your training soon !
