| | Motivated
The problem isnīt that you are not motivated, the thing is you are overly motivated. As funny as that sounds, you have to be extremely motivated to do nothing if you are doing nothing. You have a belief or value that thinks that by doing nothing you are better of than doing something. Just like depression takes alot of energy, doing nothing drains you from having energy so itīs a catch 22.
You need to work on first off all, not trying to do something, you either do it or you donīt. Either you do nothing or you do something, you donīt try doing something, you start doing it then you stop. So either do something or donīt do it, the word try is just an excuse for you to give up or in some cases not to do it at all.
I would think that one of the questions you should be asking is how can I do more? Instead of asking why arenīt I doing more? Chances are that you will get two very different answers depending on which question you ask yourself. Actually that is also one of the things you should work on if you lack motivation. Ask yourself better questions. Asking questions in a negative and unpowering format like "why arenīt I" will give you all the reasons you dont. Asking things like "how can I do" something will empower you, and you will get answers that have a motivation factor built in them.
Hope this helps.
