Education
Investing in stocks, for example, is sometimes a bit of luck, but it's good to have some skill and some knowledge that you learn through some self-education.
Such self-education includes books,videos, platforms, websites, social networks etc... .
Personally I find it better to start from simple books for example, where one learns all those basics and necessary things to start with.
As such starting books I could recommend for example The Psychology of Money or Rich Dad, Poor Dad. I think these books are great at showing the whole system of how it works, you get to read why you should invest and learn the basic rules.
Then you can move on to more complicated books like The Intelligent Investor or some analysis guides etc...
But it's definitely good to have another source of information, like some platforms like BULIOS and then you can also learn something on social media, but there again beware of scams and possible false information.
You can write about how you educate yourself and your approach to it.
Alternatively, you can write your favourite book.
I used to listen to podcasts, now I read books and various websites.
For me, I guess I'm dominated by listening - podcasts, as I can do it anytime - driving, running, etc. But I still include books, then of course technical articles, annual letters, but generally if I find an interesting topic or concept, I like to look it up myself on the internet.
