The world of your thoughts is purely interpretative.
The world of YOU (your ego) is purely interpretative.
Think all you want, know all you want, but none of that really matters.
Not until you use it to make a dent in the real world. 
You have two identities. You existing presently, and the you you leave behind when you die. The latter becomes null if you neglect the outside world; if you neglect action. Being alive gives you the ability to do above all else. So do something!
