ISTJ Style of Fun

My husband, a true ISTJ (Introverted Sensing Think Judging), was recently asked what he does for fun. This question left my husband at a complete loss for a response. Why? Doesn't he have fun?

The problem is that ISTJ's often do not lable the things they enjoy as "fun". "Fun" is a flighty term. Most of what he enjoys comes under the category of "it needed to be done".  Sure, if pressed, he might admit that he enjoys fixing and building things. Does he think fun is bad or a waste of time? No, he just thrives on accomplishment.  ISTJ's love to make lists and cross the items off.

For a personality which has a very high tolerance for repetitive details, likes to schedule, values accomplishment,  and only "plays after all the work is done",  play is a serious business. Always seeking for improvement, they measure how many baskets they got, steps they ran, ski runs without falling, laps they swim. Organized sports such as baseball, basketball, and volleyball where lines are drawn (literally) and rules are clear are favorites of the ISTJ.
