In my experience, that's the best way to learn. I think a lot of people are scared off by intellectual challenges that seem insurmountable because they underestimate what persistence can do. I think my most important lesson in uni was not to give up, even if you feel like the subject matter might as well be in a foreign language. I distinctly remember sitting and reading documents on cryptography for a larger project and it was all more or less unintelligible to me. When it was over I explained all of those concepts and more during my presentation, and even got the highest possible grade. That was accomplished by simply repeatedly banging my head against all the theory while researching it and reading different explanations and trying to go at it from different angles.
