I personally ended up in IT because "why not it pays well and I like computers", I wasn't the same person when I chose that path and now I'm actively trying to figure a reasonable way out.
> There are only a few who control themselves and their affairs by a guiding purpose; the rest do not proceed; they are merely swept along, like objects afloat in a river. And of these objects, some are held back by sluggish waters and are transported gently; others are torn along by a more violent current; some, which are nearest the bank, are left there as the current slackens; and others are carried out to sea by the onrush of the stream. Therefore, we should decide what we wish, and abide by the decision. - Seneca
I liked computers too, ever since my (divorced) dad showed me one. But why did I find them so interesting? Probably because I mostly played / occupied myself alone as a child, I read books while other children preferred "stupid" outdoor activities. We don't do what we're told, we follow whatever suits our personalities, at least if we have a choice.

You don't need to buy into the dogma, but some of the buddhist authors have developed great mental practices of dealing with fear, for instance. As an example author, I thoroughly recommend Thich Nhat Hanh.
Self-compassion also has great benefits in the business world, as you learn to understand and listen to your counterparts better, instead of being driven by a selfish agenda. This is, of course, just a by-product and not the main dish.
