Where do I start with absolutely 0 note taking skills?

I’m struggling with keeping track of info during meetings and tasks at work. I’ve never really learned how to take proper notes, half the time I write stuff I never look at again, or I miss the important points completely.

Any simple systems or tools you’d recommend for someone starting from zero? I’m open to digital or pen & paper, just want to be more organized and not feel lost after every meeting. Thanks!
