I read a report where older people were asked: If you were in your 20s again, what would you do? Almost all of them came to the same conclusion. They said they should have simply done what they truly wanted and taken the risk to do it.

Without overthinking it or planning everything endlessly, because life passes by too quickly. Later on, you start a family, you work a lot, and you get caught in a routine, an everyday cycle.
Just do it. Take risks and do what you actually want to do. You have to find the courage to simply start and free yourself from the things that make you unhappy in your 20s. You’re still young enough to fail, and to learn from it.
