I love trying new things! So much so, that I don't stick around long enough to finish the things I started trying in the first place. For me, it isn't trying that is so difficult, but it is the perseverance after the initial try or sticking with something after the initial luster wears off that has proven to be challenging for me. I'm definitely lacking a consistency to my effort.
It is difficult, especially if the things don't have enough "pay off" in terms of activity.. Why keep going at something that doesn't excite us?
Some will do it for money though :)
For many, money is the payoff that keeps them coming back. But it has diminishing returns if the situation is hard to manage.
