I’m not superstitious at all but out of habit I do tend to (moderately) follow a bunch
Don’t put new shoes on the table
Don’t open umbrellas inside
Don’t walk under ladders
Don’t walk over 3 drains
Don’t pass people on the stairs
Throwing salt over my shoulder if I spill some)
Pointing out the good luck of being poop on by a bird
Greeting/saluting a magpie
