They are tolerant, flexible, quiet observers until a problem appears and then they act quickly to find a workable solution. They are good at analyzing what makes things work and readily get through large amounts of data to isolate the core of practical problems. ISTPs are interested in causes and effect and organize fact using logical principles while valuing efficiency.

“Doing The Best I Can With What I Got”

Rather than some sort of vision quest though, ISTPs are merely exploring the viability of a new interest when they make these seismic shifts.

I wanted to live the life, a different life. I didn’t want to go to the same place every day and see the same people and do the same job. I wanted interesting challenges.
Harrison Ford

ISTPs love to explore with their hands and their eyes, touching and examining the world around them with cool rationalism and spirited curiosity. People with this personality type are natural Makers, moving from project to project, building the useful and the superfluous for the fun of it, and learning from their environment as they go. Often mechanics and engineers, ISTPs, find no greater joy than in getting their hands dirty pulling things apart and putting them back together, just a little bit better than they were before.
