Have an Answer?
I think everyone feels this way at some point in their life.
Unfortunately, its not something someone else can answer for you. And honestly, I don't think you want anyone else to answer it for you even if they could as the most important part of life is the journey itself. That being said, perhaps I can help you look at the question in a more manageable light.
For me its crippling to think 'what do I want to do with my life?' as if you can only choose one thing and could possible hate that one thing. It becomes much more manageable to think 'what do I want do NEXT with my life?'. We can do many things and we don't have to have a single answer. Plus, there is no wrong answer. If it doesn't fit, learn from it and build on it as you move onto something else.
I am not Buddhist but I take this Buddhist teaching to heart: Its the journey that is important, not the destination. Enjoy the ride.
