It would be easy to blame a lack of attention, or a clinical disorder of the same, but taking on a new hobby or creative skill and watching the shininess of it fade quickly is not a disorder of self, it’s just the math of progression.
Maybe you have just taken up study of a new instrument or have picked up the supplies to tackle an artistic medium you’ve never before dabbled in.
Your first attempt to create is going to be one hundred percent new progress.
Your second attempt is going to build on that newness, so it will not be all new, but there is still so much to learn.
Your third, fourth, fifth and so on for the first dozen explorations of your new interest will yield progressively less new growth, but still represent a lot of new.
But then eventually (and soon) the newness will plateau. It will seem for all the effort you are putting in you are barely experiencing anything new, barely growing, barely learning. (Even if you are, in truth.)
And there’s the root of the equation. Our brains like the newness. We are rewarded with a hit of dopamine, a feel-good moment of joy for experiencing something novel, and those hits come with decreasing frequency as we move from being a beginner in the early stages into a student practicing yet-to-be-honed talents.
The math isn’t on our side. So we need to calculate a way to keep our interest and push through towards mastery.
