I´ve been thinking about this topic (information overload) lately and my conclusion is that the problem actually comes from not having a structure and not asking the right questions in the right sequence.
For example, when I´m about to learn something new, let´s say “Instagram marketing”, the first question I´m always asking (and trying to find answers to) is: “Is this going to work for MY specific business and is it worth, investing time to learn it”.
I´m looking for case studies, testimonials, etc. which provides proof that Instagram works for my type of business. If I don´t find sufficient proof or the “proof” doesn´t look legit, I just pass on this and move on. If I do, the next “step” and goal would be to find an “ultimate guide” which gives me an overview.
From there, I go into more and more details, but only if they are relevant – for example, if it turns out that Instagram will work for my business, but to make it work, I´ll have to become an influencer, I´ll do research on How to Become an Influencer.
If, on the other hand, making fancy pictures isn´t important for your success on Instagram, don´s spent (or waste) time on reading how to make fancy pictures and what tools to use, how to use them etc. Just “invest” your time wisely.
The key point is to KNOW and make sure that the information you´re looking for and consuming is really KEY and necessary for your goal (and of course – quality!). If you don´t do this, information overload might occur.
