Pick your one thing as early as you can and become an expert at it.

There’s an example I heard of a top tax lawyer being very happy with the way their life has worked out after a couple of decades or more working in a narrow, perceivably dull, area.

Go deep and narrow. There will always be good things going on there the longer you stay in the space, learning and evolving.

The tax lawyer will be satisfied at the end of their working days once they retire, financially secure, with a legacy earned from a raft of loyal clients.

They may have built their own practice or just be a well-known expert in the space in high demand.

Assume you can do this for yourself and work hard to achieve it in your space.
