It's easy to want to just sit back and be entertained by other hardworking individuals. There was this beautiful girl I had a crush on with Facebook; she's still a friend but I sort of got bored with her appearance now. It seems like she's gaining a little weight, but like that really matters. The physicality isn't that important to me, but it seems like a good number of people still admire her funny or bold expressions.
I think sometimes having these worn out and lazy feelings while still working is a natural thing that you just have to overcome on a daily basis. Sure, it's probably normal to not want to put yourself through a pain-inducing workout on your body for a daily basis. Being baffled and angry underneath from having a hard time is also normal too. All of those negative and mixed emotions is just completely normal to have and to be able to work it out and still get through the day is what being human is about!
