What investing topics are you the most interested about?

I am curious if there are any topics related to investing that you are particularly interested in? Of course, it could be very subjective depending on your financial literacy and status, but I am curious about all answers.

I noticed that many people don't know a lot of financial concepts, not just investing concepts. It is fair that you do not need to know much finance to invest, but sometimes I come across surprises on how much money is being invested without truly understanding the ways around it. Of course, it is good to start investing, and I would also rather just start with minimal knowledge and pick up the rest on the way.

Nevertheless, what are the concepts that you would like to learn more about? (Also, if you could specify for how long you are investing now and/or your background for context would help a lot!)
