Is it normal that i don't know what i think about anything?

An agnostically inclined mind. A certain kind of intelligence you have, yes indeed.

I was very much like that as a teen, and wanted to know.

If you want conclusion, maybe read some philosophical works and let the authors poke holes in the questions for you, allowing you to see truths more easily.

Many people are too dumb, stubborn, lazy or lack the reading skill. I've poured over many books from dostoevsky to Sartre, even Ian Brady's book. And it's worth it, most certainly if you are the type of person you describe.

I wouldn't worry about it. I think you're better off than the rest of us who are set in our ways and think we know things. But there is a difference between accepting that our knowledge is feeble compared to the whole, and being apathetic.

There is a certain wisdom in uncertainty

I know exactly what you are talking about.

I traveled as a child and know a very diverse collective of people. My parents and my family members all have very diverse opinions, both religious, philosophical and political and I wasn't brought up with much of a set doctrine other than the typical military doctrine: Treat others with respect, have respect for authority, the hierarchy, don't expect more than you're willing to work for and no one owes you anything that you haven't earned.

Understandably, that doctrine has some influence on my belief systems, but I have found that there is truth in many belief systems. I have spent a lot of time trying to find a middle ground but you must understand that only a fool would think they have all of the right answers to every question and that to not be able to cope with the idea of questions being left up in the air and truth being fluid is a major sign of insecurity, insecurity that a lot of people have.

People want certainty and don't want to accept that truth isn't something that is always solid and unchanging and it isn't something that can always be found in one place. They just aren't comfortable with the idea of "maybe it's this way, but it could be that way" and the concept of an unstable truth is scary. However, we don't need to have an opinion on EVERYTHING. We think we do, but we don't. In the end, it's how we treat others and ourselves that matters.

Go with what feels right as opposed to what you think is right if that makes sense.

You'll figure this out all by yourself. Give it some more time.
