5. SET UP MULTIPLE USER ACCOUNTS FOR DIFFERENT MOODS
Netflix lets you set up a maximum of five different logins on your account; most people use this to let other family members share the same Netflix account. But even if you're not using all of your login slots, those extra user accounts can still come in handy.
Set up one account for ‘Serious', when you're in the mood for political thrillers and tearjerker dramas, and one account for ‘Silly', when you're in the mood for Harold and Kumar or anything starring Seth Rogen. That way your viewing history will be separated, which will make viewing recommendations more accurate.
Or try setting up one account for yourself, one for your significant other, and a shared account for joint viewing, that way those period dramas you only watch together won't interfere with your individual taste for Nazi Dinosaur-fighting spy comedies.
