Brand, thing, behavior, method, advice, mantra, etc.
I swear by Blackwing pencils.
Also, the 'two minute rule', which has really improved my life: "if it takes two minutes or less to do, just do it now; if it takes longer, schedule it." I've got untreated attention issues and it's very easy for me to notice something needing done, and overlook or procrastinate it because it seems inconvenient in the moment. Having a totally painless rule that forces me to acknowledge that thing I should pick up, that trash bag I should change, etc, or, to at least put on my calendar anything I mustn't forget in the long run has been great for me.
No-one ever lay on their death bed wishing they'd done more ironing.
On the whole (unless it's necessary for a professional environment) it's a waste of time. I iron nothing, and got rid of my ironing board because it was just getting in the way. I've kept my iron just in case, but last time it was used was about 5 years ago when a friend was staying who needed to iron a shirt for a funeral.
Distilled water has no dissolved solids, so when its turned into steam it leaves nothing behind. If you use regular tap water you’ll be eventually left with crusty calcium buildup on the nozzle of the device.
Some devices, like hand steamers or Kurigs have thin internal tubing for all this super hot water that goes through them. That makes them prone to clogging from mineral deposits, and they're basically impossible to clean manually. Vinegar can help with buildup, but then you have to deal with the vinegar smell.
So just use distilled water instead, as if it were a CPAP.
