Days look so short for me

I dont know what to do first.. i dont know where to start and almost every day, when i´m going to bed, im thinking about thinks i havent done.

do day feel for you also so short? or am i just bad at time-managment?

I feel like, some day im with my friends, than i go to bed and i´m missing some work, the other days im working all day i feel so lonenly.
The worst thing, which can happend to you, is discovering new series...
When i found out Game of Thrones.. i was fucked up for one whole week until i haven´t seen all of it.

But actually what do you think is the best way to spent your time?
Improving yourself?
beeing with community?

I would like to do things when i feel it.. when i feel it´s right time to go working.. i would like to go.. same with the other things, but then i endup doing everything, but nothing worthy.. 
Maybe im just thinking too much.. 

Have a nice day!)
