Watching an escaped helium balloon float giddily through the sky.

That moment when you are in the flow, you are so focused on the task and get so much done, hours pass by and you don't even realise it but you feel good.

Pressing your back up against the wall after a long, hot shower and letting the coolness wash over you.

The satisfaction of closing like 100 Chrome tabs all at once at the end of a long project.

The epiphany that breaks your trance in front of your screen.

Throwing your smartphone out a window.
