How do you remember information from IT webinars?

Question

IT education

For example, I write everything down in a notebook, which I never open later. But I don't see any alternative.

Answer 1

I just listen, doing some other things in parallel, the subcortex of the brain records the data in the background, then when it needs to be done, the brain works according to the principle “I remember it’s still possible there” + light google and we find the recipe.
PS Now there are so many webinars that if you watch everything seriously, then you won’t have time to do anything else, only watch webinars for 10 hours a day))

Answer 2

ask for a copy of the presentation to the mail, which you will not open later either. but suddenly?
