If you want to rapidly increase wisdom, you must be willing to jump from one thing to something totally different. This only works, though, if you truly commit to the first thing before switching. For if the knowledge that you’ll never be anywhere for all that long leads to ambivalence, so many of the gains from doing a bunch of things is lost: you never, actually, did anything. Not all that well, at least.
There are benefits to long-term commitment, to being a “sticker.” A skilled “jumper” accepts this reality and attempts to close the gap by going so very hard while in any one thing. Instead of ambivalence, he realizes how fleeting it all is (by choice, sure), and doubles down efforts to suck as much value before it ends.
It’s much easier to live every day as if it’s your last if you know tomorrow will be totally different.
