Be a generalist
If you play the guitar, you’ll need a singer.
You will never be able to play good music on your own.
Always dependent.
People became specialists because the market pays better.
But it is sad to be always dependent.
That’s why you should be a generalist.
If you're a software developer, learn UI, UX, marketing, backend and frontend.
If you're a engineer, learn to build a whole house.
If you're a musician, learn to sing and to play the guitar.
If you know how to build, learn how to sell.
Humans were not made to be specialists. Be a generalist.
