When im working on a project and I get tired or have the urge to do something else I try and work on my personal blog, give out tips, help others and do more so I'm still working but its not my main concern, I like to play netflix in the background like a funny movie or something as well or even loud music it helps me work.. I alter out all the noise except for the music than go straight to work

Research, learn a new programming language, make plans and you will never be between projects, I always have four or five projects running, though dec and jan are usually a bit slower.

Always be marketing your services. Does listening to YouTube videos make you money? If not, then do something that will.
