Compliments are gifts - not sharing one is like keeping a gift in your pocket: with one person complimenting another and it feeling like receiving a gift

Compliments are gifts

Compliments are gifts is a lovely metaphor for making the world brighter. I can’t remember where I heard or read it, but I have found that when I think of a compliment as having a gift for someone, if I don't let them know my compliment, then it's like having a gift with their name on it and holding it back. This reframe has made me take the time to share compliments more often with friends, colleagues, shopkeepers, the person who always has a cheery smile in the morning, the person who organised the event, my kids, my wife, and pretty much everyone. And life seems a better place. Do it! Thank you for following and checking out this sketch. It’s a privilege. Also, accept compliments.

Rewrite to avoid click here

I find myself linking to this article about why your links should never say click here for links on the web that I thought I should just get it down for easy reference. The solution, generally, is to rewrite your sentence. For more about writing for the web, click here. Only joking, check out more tips about writing for the web. Also see: Omit unnecessary words, use styling instead of colons, cognitive overhead and the best writing is rewriting.

what is a Phoenix tree explained with a toppled tree shown pencil-sketch style with its roots still connected at one end, side branches along the trunk becoming trees in their own right, and one putting down roots

Phoenix trees

Phoenix trees are trees that live on after toppling and that can create new trees from branches of the original with their own roots and everything. They are named after the mythical phoenix, a bird that rises from the ashes to regenerate after death, much like Fawkes from Harry Potter. In phoenix trees I've seen, a large toppled tree hasn't completely separated from its roots—where some roots are broken as the tree fell, one side of the roots has managed to remain connected. This provides a lifeline for the now horizontal tree. Remarkably, those branches along the trunk that are now growing upwards can become like trees in their own right and, at times, even put down their own roots. These side trees remain supported by the original great, toppled tree.  Phoenix trees are not to be confused with nurse logs which are dead fallen trees that provide a great environment for new trees and plants to grow in.

What is the Fresh Start Effect example explained: a brave person thinks challenge accepted on Monday 1st January thanks to the Fresh start effect from Katy Milkman

The fresh start effect

The Fresh Start Effect explains why we’re more likely to tackle meaningful goals or form new habits at the start of a day, week, month, or year. These fresh beginnings—like a birthday, moving to a new house, or even a Monday morning—are powerful mental triggers that motivate us to take action and start anew. It’s fascinating how the simple act of marking a “start” can make us more open to change and new challenges. Whether it’s the first day of the year or the start of a new chapter in life, these moments provide a sense of renewal and opportunity. We explored this idea on the podcast: Listen to The Fresh Start Effect on the Sketchplanations podcast You can also hear about it from Katy Milkman herself, Professor at The Wharton School of the University of Pennsylvania, on the Freakonomics podcast: When Willpower Isn’t Enough.

How to remember if it's a Stalactite or Stalagmite (or stalagtite or stalacmite): Stalactites Cling tight to the Ceiling of a cave. Stalagmites Grow on the Ground

Stalactites, Stalagmites

How do you remember the difference between stalactites and stalagmites in a cave? And how do you spell them? A simple mnemonic that’s helped me is this: Stalactites cling tight to the ceiling. Stalagmites grow on the ground For Stalactite, the "-tite" and "tight" remind you of the ceiling connection, and the letter “C” in stalactite fits perfectly with “ceiling.” For Stalagmite, once you’ve got stalactite, stalagmites naturally become the ones that grow up from the ground, with their cheeky “G” matching “ground.” Easy, right? With this trick, you’ll never mix them up again, whether you’re exploring caves or acing a quiz. Sorted.

What is the IKEA effect example explained - sketch shows a person that put an IKEA table together by themselves, and although it's not a perfect build they still love it, because they put it together

The IKEA effect

The IKEA effect is the increase in value we feel towards self-made products—products that required our effort to create them. Or, less formally, we love it more if we made it. The effect is named after the odd sense of satisfaction many of us feel after spending more time and sweat than expected putting together IKEA's famous flat-pack creations. Yet not only does more effort equal more love. If we've put effort into something ourselves, we're also more likely to, often mistakenly, think that others will value it more, just as we do. Together with others, Dan Ariely, a professor of behavioral economics, conducted several experiments leading to these conclusions. Ariely also points out that kids are the ultimate expression of the IKEA effect: they're very hard, don't come with instructions and take a lot of effort. Watch Dan Ariely do a great job explaining some experiments that lead to this conclusion, or read the full paper, The “IKEA effect”: When Labor Leads to Love (pdf), Norton, Mochon, Ariely HBS working paper, 2011.
