You can focus on doing one thing well, or you can try to do a lot of things.

You can stay disciplined for many years, or you can become distracted by the next shiny trend.

You can develop one particular skill to an elite level, or you can potter around with many.

You can keep going when it gets challenging, or you can quit and try something else.

You can set a non-negotiable standard for your work, or you can hope that no-one notices.

You can go deep, or you can go wide.

You can become a master, or you can stay mediocre.

But you can’t be both.
