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

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.
