"I don't know what I'm thinking until I've talked about it" may sound strange to those who believe that analysis should precede thought and yet it may be that an equally large number of people are in complete sympathy with the approach. They need to engage with others in order to clarify their thoughts. For them, analysis arises during - and not before - discussion. Still others may withhold analysis until the very last stage.
Such style differences extend, of course, to other areas. Some people isolate themselves during a crisis while others engage. [There are many gregarious loners out there.] Some need company during sorrow while others crave solitude. Some hunger for praise and others are embarrassed by it. Some love intimate dinners and shun the large parties that are so enjoyed by others.
It is important both to know your style and to respect ones favored by others. Consider how often you have to restrain yourself from imposing your way on a person who has chosen a perfectly acceptable alternative. Develop that filter. Hold that tongue. It will save you from a lot of time wasted by wondering, "Why can't they be more like me?"
