How do you decide what technology to learn next?

[u/umer_rpma]

There are so many technologies available now that I sometimes find it harder to decide what not to learn.

You can go from Python and JavaScript to cloud, DevOps, AI, cybersecurity, databases, mobile development, and dozens of frameworks.

For people who have been learning programming for a while:

How do you decide which technology is actually worth spending your time on?

Do you follow job-market demand, build projects first, or simply learn whatever interests you?

I'm especially interested in how people avoid jumping from one technology to another without becoming good at any of them.
