Maybe this is kind an out of topic post, but i want to share my experience about my laziness.
I have a startup that almost finish ( the apps system, homepage are done ) Only a few pages like portfolio, about page, features, pricing, etc.
I feel like i am exhausted after 7 months of development. I work this startup by myself, i have lack of skills in web programming. I was on fire in a previous month but i feel myself so lazy to finish this startup.
This is not my first case, i was vacuum and waste 2 months for gaming when i am working on the apps system which is now has been finished. Because i always have a thought like this on my mind
" That can wait, i need to refresh my mind " But the reality is i abandon that task
Sometimes i feel bad for wasting 2 months for nothing
My question is anyone here experience the same issue? My friend said that i need zen like go outside, etc 
Sorry for my bad english
