why don't you work on two schedules, the first being a strict weekly or every two weeks schedule (1-60 seconds videos that you can start and finish in less than 3 days,) and the other is a loose schedule based on either quantity or compromise, but the content needs more effort and production time for example (6 songs a year, or 4 songs and one long documentary, or however you choose to balance it,) won't that take away the pressure of taking a long "break" then feeling that you have to make something good.
yes, i did this in early 2015. what happens is, the 'long' items take much longer than you've expected, and it's made even longer because you're also constantly having to do so many short things
