I follow some rules:
# 01: Once the download is complete, I have to watch anime (not immediately, but when I would want).
# 02: If they prequel, sequel, Ova, movie or something, I have to watch it.
# 03: Because of the 02 if a new content out on something that I have seen, I have to see it too.
# 04: I can not drop or pause an anime, I have to watch it entirely
Good or bad, I shall always look an anime with these rules.
For the rest I expect a season to be over to watch it unless there is a sequel (ref rule 03) or in this case I will look every week.
In this perspective I see the winter season during the spring and when finished, pending the end of spring I pass in "off season" which means I watch the older animes like some masterpiece that I haven't seen yet.
