Last chance for a career shift

Hi guys

I will just briefly introduce myself. I’m a guy in my forties (44), and I really find it, it’s the last possible moment to make a career shift.

I’m tired of my 23 years working as a production planner.

I’m good in tech and computers, also know some HTML, CSS and JS programming

Maybe a stupid question, but what would be a good thing to start doing online?

The more articles I read online the more confused I’m getting

Some say e-commerce is dead, some say dropshipping is dead, blogging is dead

Where to start then?

I also found some writing experts on Twitter (now X)

What are your opinions on these writing experts teaching how to earn online:

• Justin Welsh
• Dickie Bush
• Alex Colhoun

Is it worth buying their courses?

Thank you for any kind of advice
