Many people don’t know what they want it seems that there is a misconception that people find themselves and find what they like to do.
You solve this problem by picking an occupation and sticking with it.
You can’t find yourself if you don’t try anything, because your findings are simply theoretical not practical.
You can’t experience new things you’d like in your head.
If you like theory try philosophy and writing, talking, if you don’t like philosophy and are more into practical things try things that don’t have a big learning curve: driving a bicycle, skating, skying.
If you would like something that needs a lot of work, try guitar, piano or any musical instrument like harmonica.
It’s easy to start but hard to master.
These are just examples hence you can pick any occupation within your life. Look at life like a video game or just play a video game and become an expert in it.
