In many instances I used to admire people who have this strong personality inside them (crystals), but in other times I prayed to god to never become like them when I see how much they are unable to let go of their holy cows. At that point I see a robot in front of me, not a living human being who can think rationally.
I would still like to crystallize, but just not to have something that would block me from my essence and having an open view on the world.
Since I can relate to not having a "drive for life" for most of my life (a bit of tautology here ;)), here's an idea. Is it possible that you don't want to "crystallize" but to have a "maturity of character"?
In many cases really "driven" people are being motivated by things they are not aware of. And sometimes it carries a heavy price for their health. I have a friend like this, who wants to work as a doctor at the top veterinary clinic in post Soviet Union area. She works as an assistant there right now. Sure, she is super dedicated and works incredibly hard for that chance. She takes 16 hours shifts one after another, and that's why she definitely deserves it.
On the other hand, she suffers from a serious case of parasomnia (and I had a chance to experience it when came for a short visit). During a day she is an epitome of tranquility, but during sleep she moves, fights, makes noises as if in pain, even says things like "I am afraid". She also says that sometimes she sleepwalks. Sure, apparently she has it from childhood, but it probably means that she always has been a "driven" person. And I really worry for her, because this isn't going to end well. But obviously she doesn't want to hear any of it.
But there is another type of "strong personality", that has to do with "strength of character". In this case "strong" doesn't mean "crystallized". This kind of people can "bend" and adapt if needed, but they also have enough will to face inner turmoils and prevent them from interfering with their aim.
That could be a good alternative to "crystallization". :)
