Basically you know what you like even if you don't its definitly not oh perhaps i like these things because thats the most ridiculous thing i have ever heard you can force yourself to like things but thats not your problem your problem is you are lazy and don't want to do anything you are just coming up with an excuse for yourself so you can lay around all day and do nothing. You know what you like just think of the things you enjoyed in the past or if you don't feel like remembering do stuff you like now if you like tasty food become a chef if you like sleep learn about the human mind and the nature of dreams become a psycologist or something. Just go with the flow if you are interested in something pursue it if you think you might like extreme sports go do research find a place that offers lessons rent some equipment and go for it don't sit here don't make catagories go do something.
