As I can't be bothered to even check which ones to delete, I will definitely not be updating any of those.
I think I remember just these passwords: my 2 banks (that keep my savings), stock broker, primary email a/c, AppleID, personal VPS. For these too I keep very personal hints (no one else can guess) in KeePass (just in case).
Master passwords for LastPass and KeePass are quite difficult and I don't keep its hint or anything anywhere. It's a risk I decided to take. On the downside I have not changed these two passwords in a long time.
Rest goes to LastPass (100s of them).
So like, Abzysbej@10netflix and Abzysbej@10hulu

Note that I don't advocate this strategy for high-security applications, but for throwaway accounts that you might want to access when not having access to your password manager it might be useful.
