Gym membership

I just got back from the gym today. I am very proud of myself, I did 20 minutes on the machine ( i think it's called cross trainer). Some people love their exercise and they do long hours, i know that's not the case for me. One lady that i saw the other week, has been in the gym forever and she is still paddling the same bike machine. I envy those people, i wish i have the passion and persistence to go to the gym year after year. I don't find gym enjoyable, i know some people do. I like sweating and work on my muscle, but may be in more enjoyable way. I like bush walking, kayaking and ballroom dancing that would be more enjoyable for me. I am currently trapped in the 12 months contract gym membership. As I said to my friend the other day, my new year resolution is to not get sucked into good looking and smooth talker gym sales person anymore!!!
