I do a lot of streaming and thus have a webcam, and it's hard sometimes to remember to look at the camera properly. A hack I picked up from someone who does a lot of webcam based interviews - stick googly eyes on the webcam where you need to be looking and make eye contact with them so you're not tempted to do so with the screen/person on your screen. Makes you look a crap ton more professional, and if you're the kind who would giggle at googly eyes just put regular eyes printed from the internet or drawn on paper or something.
A few cleaning hacks; you can make just about anything for cleaning yourself, as long as you watch what chemicals you're mixing. For example a mixture of vinegar, borax and water can make a great non-bleach alternative to toilet bowl cleaner and mildew remover for showers. Great for those sensitive to bleach and/or its smell, or those with pets who are worried about its affects. It's super cheap and easy to make your own laundry soap, and better for the environment - Google has some great recipes for this. Need a carpet cleaning powder? Combine some ground herbs with baking powder (rose petals and lavender buds, for example) and sprinkle in the carpet then leave for a bit before vacuuming up, takes all the odors out with it and helps draw dirt to the surface without any harsh chemicals, again great for those with pets.
Need shower products? You can make your own bath bombs pretty easily and if you want them to fizz it's just citric acid which is easy to get. A mix of sugar, used coffee grounds and a carrier oil (coconut, jojoba, even baby oil!) makes a great one for your general body by removing dead skin and smelling great, though if you have sensitive face skin it's not a great idea and sugar + lower body parts don't mix so none of that. A similar mix with some lemon juice makes a great smooth leg bit too, you basically shave and then slather it on and then shave again like shaving cream.
Honestly I have my own recipes for all of these things but they're made of trial and error and personal preference. It's one of those things that most people just don't realize it's super easy to DIY so I suggest hitting up Google and finding some recipes then tweaking to make your own variation with your own preferences.
Oh, and for food? Any time you're making anything with chocolate if it calls for water replace the water with coffee, and if it doesn't but you can get away with a bit of liquid add a little coffee anyway. Really brings out the flavor of the chocolate, especially dark chocolate, and doing this for things like cakes and brownies has brought me a ton of praise over the years :)
