Well maybe it is time for you to start doing what you should be doing? Wrong definition.
The things that excite you and you think you should do someday in the future. This is what you really need to do and deeply want to do. The future is now. They won’t happen if you postpone them constantly. What will eventually this lead you to will be disappointment, unhappiness, dissatisfaction and stress. Despite that, as Steve Jobs and many other say “…in order to produce great work, work that changes the world you really have to be excited by what you are doing. How else are you going to put that extra effort that will make your work exceptional?”
