You can. It's called therapy.
Still, I think your point is largely fair and correct. Easy to agree with the headline, in that you likely won't optimize your way to being a good person. But you can use optimization ideas to remove things that are making you not a good person. Indeed, the main optimization idea is to measure something, and then take action to move it in the direction you prefer. If what you are doing isn't moving in that direction, you aren't optimizing for it anymore.
so, no
I don't think you understand what optimizing entails.
Optimization is inherently antithetical to balance, in principle.
Optimization is looking for local/global maxima. Balance is releasing the need from seeking local/global maxima entirely.
I mean, you could try to seek balance through optimization. Good luck with that.
The implication of your statement is you eventually reach some global optima. The reality is you become over-aware of some things and under-aware of others. This is the local optima and you've been caught in a bowl. Therapy "works" when your local optima is "good enough" for your own definition of done. However, it can often take several "bumps" out of those local optima to find it and once again you haven't really "optimized" like you are implying.
I would think the focus on optimization of emotional and awareness skills would simply lead to more, not less, anxiety. It sounds like the same problem people have with always being online and being a good "global citizen". In this example, like your example, when you feed your learning algorithm data about some war in a far off land you necessarily reduce the weight on your immediate surroundings.
Therefore, I believe it's impossible to "optimize" such things without making significant learning losses. Better to succumb to the brownian motion of life - imo.
