ELI5: Why do we continue behaving irrationally even though we fully understand that our particular behavior is irrational?

For example: shyness, dating, acquiring new habits, negative thinking.

The way we behave involves thinking (or perhaps not thinking and only acting out emotions) and emotions. The way we feel and the way we think feed off of each other. Feelings can be irrational and can overpower our rational thinking. Changing the way we think about situations (i.e., cognitive behavioral therapy [CBT]) can help us change the way we think and, in turn, feel, so that we can behave in a more rational manner.
