This is my test area for webdev. I keep a collection of code here, mostly for my reference. Also if i find a good link, i usually add it here and then forget about it. more...

You could also follow me on twitter. I have a couple of youtube channels if you want to see some video related content. RuneScape 3, Minecraft and also a coding channel here Web Dev.

Suggests that in many situations - especially in relationships or arguments - insisting on being right can come at the cost of harmony or peace of mind. It implies that prioritizing your ego or the need to win an argument may damage relationships or personal contentment, whereas letting go of that need (even if you’re technically right) may lead to greater happiness.
