Here some resources I found useful:
A lesson by Patrick Winston about presentation and public speaking.
The 40 question to ask yourself every year by Steph Ango, also available as 40 question to ask yourself every decade. .
Here are some blogs and websites I took inspiration from:
Meadow is the builder of Mire, my favourite rss reader;
James' Coffee also makes a very promising rss reader and his website is very curated;
Steph Ango is the CEO of obsidian, a famous note taking app. Steph made an amazing color scheme called Flexoki that I am using for this website;
Alfie Jones is the creator of a light/dark mode toggle collection you can find here;
Timothy Miller has a great tutorial on using Obsidian with 11ty.
