I call it being a generalist rather than a specialist, and, frankly, I prefer it that way.
As much fun as the current passion at any given moment may be, there's always something else around the corner and I'd really feel I'd be missing out if I wasn't free to pursue it. Even if this means I won't become a 'master', I'm usually still way above average, so that's okay. Furthermore, as I stated in another post, these passions seem to recur at intervals, so there's always the opportunity to widen and deepen my knowledge at a later point. This is how I have mastered my very first and oldest passion by now, and that experience too helps me be more relaxed about all the others :wink:
