General description of the ISTP
* - Likely to pit themselves, or their technique, against chance, odds, or fate.
Depends on if I think the risk is worth it. 
* - Play on impulse.
A lot of the time, yes.
* - Seek thrills in play.
For sure.
* - The managerial style negotiates with ease and has, of all the types, the highest sense of reality. He is a natural negotiator, but other titles which might . . . .
I am NOT a negotiator. If it needs to be said, then say it. None of this sugar coated stuff.
* - Ready to try almost anything once.
That's the fun in life!
* - Don't tread on me because I don't know how I'll react.
YES! And watch out if you tread too much and too long!
* - Spontaneous, easygoing view of life.
Yup.
* - One can never predict which reaction to expect from them.
Most of the time I'm pretty even keeled, but if something ticks me off you will know.
* - ISTP parents do not believe in planning. They tend to wait and see what each day brings, and then do what is needed at the time.
Depends. I'm not a parent yet, but I do plan things in situations I'm stressed out about.
* - ISTPs in their general living and certainly in parenting, know that the best-laid plans go awry.
For sure...no one knows whats going to happen, so just be prepared for anything.
* - Low need to impose themselves on their children.
Probably, altho being a first born I may let my "strict" side show.
