I was a filthy casual around year 2000 when Gran Turismo 3 came out. I never started watching every single session till about 2009. I had more time due to the who recession thing. Then I kept up that pace for a few years, sneaking in practice sessions while at work... But I think I became a bit disenchanted in 2013 or so... I could miss practice sessions and even the odd qualifying session. During the Mercedes eras I could consciously miss particular races, the boring ones without feeling any regret. I would try to watch recordings later in HD if I could.
I have sort of gotten used to this extended winter break. Got a taste of the 2020 cars to suck on like a little sweetie... the excitement has numbed. It is all one long, dull day dream until the season sparks back into life. Its almost as if the 2020 season, if it happens will be a distraction until 2021 comes around.
