Therein lies the problem.

To want to "focus on the task at hand" and then express the desire to "try being a bit of a jack of many trades" is a mutually exclusive goal set.

If you want to improve focusing skills, then it is best to pick one thing from the "many trades" and master only it before beginning another. If the "ability to focus on the task at hand" is not really all that important in the grander scheme of things and topically bouncing around is where you find happiness, then I humbly suggest to not beat yourself up about focusing on "the task at hand."

Either is an equally valid choice which none need judge, since it is your own after all.

> I want to, no, need to improve my ability to focus on the task at hand.

This. My control of my focus has been reduced to the point of disability at times (seriously worrying, when in middle age)

But this, honestly, is at odds with it. It will be difficult to do these two things at once (source: trust me bro, but no really do trust me).

Rather I would suggest a strategy, if you want to learn lots of things: ask yourself, what small set of goals are all those things in service of? What could you gain if they all pointed mostly in one direction, and how will you keep a slow, low-level, long term focus on that direction?

(I am writing this comment to myself, as you can probably tell.)

I must develop (re-develop) planning skills, because my management of time is poor and my management of my direction in life non-existent. I have a broad set of underdeveloped talents that point to me being able to do a lot more stuff for more people if I wasted less time and just steered them in a couple of directions that will have slow-growing benefits.

Apart from progressing some life challenges, what I would like to do is design one complete physical prototype every two months, to move my brain away from everyday web development and towards something that helps people again.

I have CAD and 3D printing skills, I am learning what I would need to get work CNC milled, I have just enough awareness of embedded computing possibilities and I have a couple of interests that can be used to drive product ideas forward or at least provide a personal context for learning.

Probably photography, initially; I have already made some things and used them for my own photography work, and I have ideas for more. The goal would be Tindie-type sales or at least to get tools into the hands of like-minded friends.

I have spent the last year really developing my "CAD thinking" and now it is time to just make things, completely enough that they could be sold at a sort of boutique scale.
