"The idea behind stepping outside of your comfort zone is that you keep doing it until it becomes your new comfort zone."

No it isn't. The point of stepping outside your comfort zone is to see if it really does belong outside your comfort zone. Stepping outside your comfort zone and demanding that that be the new way, results be damned, is just as foolish as never stepping outside your comfort zone. Not everything outside your comfort zone is good and usually the only way to determine what is and isn't good is to jump in and try it out.

That's fair too. The point is that you do have to stick with it long enough that you can actually judge the results. If you've been outside your comfort zone for a long time and it's still not comfortable, maybe it's time to try stepping in a different direction. But if you just went to a meetup once and you felt terribly socially awkward and you never went back, how do you know whether it's because first meetings are always awkwards vs. you just don't click with those people?

> The idea behind stepping outside of your comfort zone is that you keep doing it until it becomes your new comfort zone.

That's kinda worse. The only good way to venture into new areas, in my opinion, is to make little steps forward, to the extent that you're not standing still "as-is" but also while you're still in control of your emotions.

This will expand your comfort zone gradually until the thing that was originally very uncomfortable, is now only slightly uncomfortable.

But going completely outside your zone over and over again? No thanks. This might work for some people, specifically people with SP temperament (http://en.wikipedia.org/wiki/Artisan_temperament) who tend to seek stimulation, but it's not a good advice for the general population.

I'm an INTP, not exactly an SP temperament. I have historically been very change-averse, almost Aspergian, enough that I almost didn't want to go to college because I couldn't imagine living anywhere but my parents' house. I moved across the country for a new job in a challenging field, and knew virtually nobody there. That isn't exactly baby steps.

It worked because I pretty much made it the focus of my life to adjust to my new situation. Yes, it was scary. It was also a huge opportunity, and I wasn't going to pass it up.

If the idea of a big change completely fills you with dread, you shouldn't do it. That's my point - you should either go all-in or not-at-all-in. But if it's only a little scary, and you think you can do it, my experience has been that it's almost always better to do it and keep at it until it's no longer scary.

Two things:

1. Take "temperament theory" with a grain of salt. It's somewhat in vogue right now with a lot of psychologists, but there are also plenty of reasons to think that it's conflating two separate issues (temperament and typology) and is an oversimplification.

2. The only way to develop your personality is to step outside your comfort zone. Your type only determines where that comfort zone is, not whether you can or should do it often. For SP (really more ESP, but whatever) types, doing crazy things physically is their comfort zone. They need to learn to get in touch with their more subdued side.

I'm not aware of any personality theory that psychologists agree on, each school has its own theories. I find the temperaments derived from MBTI to be very convincing.
