Living according to reason?

In many situations I find myself endlessly debating between options on important and critical issues in life and also in simple everyday situations. Without being able to decide what is right until “something happens by itself”. It is impossible to distinguish what is intellectually correct, what makes sense, what comes from emotions, imaginations, and so on. I don’t think this is a personal problem of mine, but it happens to every person, but the intensity of the confusion depends on his ability to think and imagine (if they are strong, it will be more difficult for him). I ask 1. Is it possible, at all, to direct life according to reason and logic. Is it possible to trust our judgment and thinking skills? 2. How do I know if I made an informed decision or an impulsive one stemming from emotions? After all, my intuition that I made an informed decision is no different from a “feeling”, as certain as you might imagine. If there is no way to know, isn’t the statement that ‘you need to make informed decisions’ a bit empty of content? 3. We can say that we should go with what is reasonable, even if there is no certainty. But what if the options are really equal? ​​4. If it is clear to me that emotions and imagination play tricks on our minds, how can we still trust this loose “reasonable”? Why should we believe it? 5. Perhaps the obvious thing is that we have no way of knowing anything, except for our instincts
