For some things yes. For others, nope. The realisation that, when you pour a full long-life milk tetrapak, the opening goes at the top not the bottom of the top face? That changed my life instantly. I mean, it’s not earth shattering but it’s had a permanent and measurable impact on me, and I’ve passed it on to a few people with similar results.

Likewise a friend once pointed out that swinging a closed sauce bottle to get the sauce to the top is way more effective than shaking it linearly. That was 15 years ago and I still think of him every time I use this trick.
