Now, this won't sound like an INTJ... but all major life decisions were made quickly, basing on intuition, because it felt right. It's important to do the right thing. It's important to do what you like and have passion for. Minor details and steps to achieve the goal can be fixed with logic but on major decisions I've never hesitated, never ran cost - benefit analysis and never regretted any major decision I've made. When I was 17, I just moved out without thinking, where I'd live, how I'd make a living, where I'd study. It just felt right. Otherwise, I'd never moved out because it didn't square financially. Then it was a thourough analysis, plans and tough choices on where to study, how to merge university and work to pay the rent and so on. But the key decision was made quickly. Similarly with choosing what to study, where to work, how to excel in what you do and get promotion, which appartment to buy, whom to date. Big picture was always coming from intuition and decision was made quickly. Minor details were fixed with logic. Not vice versa.
I'm probably happy and I'm where I wanted to be. At least in general. But you can't predict and plan everything. Big numbers should square.
