I think the biggest thing is clean as you go. Wash all your knives cutting boards dishes when you are done cooking not look at a sink full of dishes after you are done. Cleaning as you go helps keep away cross contamination and you avoid having food borne bacteria.
Falling in love is awesome but I'm never drawn to happy songs per se so whenever you sit down to write a heartbreak song and you're happily in love it's like 'OK now I have to go back to a sad place to get something good.'
