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

> Other than that near-universal constant, I want to try being a bit of a jack of many trades this year

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.

How did you develop your CAD and 3D printing skills? Did you use any online courses?
