Not speaking from personal experience, of course but it occurs to me that all that is required for ‘success’ is that one’s natural proclivities be aligned with one’s natural talents. Well, that and a whole lot of luck. 😉
There's no pattern to falling in love. At least, nothing I can understand. Not something I could see beforehand. Not something I can decipher after, either. Trust can be earned, piece by piece, like links of a chain. But love is more like faith, or belief: it's a leap. It's hurtling over the edge of the cliff and trusting you will not drown.
