I never aspired to be a generalist, but I have come to realize my process has made me into one.

If I had to generalize how I work, I'd say it comes down to:

1. Identify the highest value thing I can work on that is feasible

2. Learn what I need to finish the work. Invest as little time/effort as possible into topics that have not proven to be timeless. Lindy's Law is your guide here.

3. when the solution is good enough, go back to 1.

Being a generalist doesn't mean you aren't an expert in anything. There are topics that I've identified as being so timeless and high value that I've more time and effort into them than others (making me a relative expert, I guess).

For me, it is more about targeting the goals at hand and learning just what I need than setting out to master the tools I like. Over time you will become an expert in the tools you trust.
