Just as an aside, apologies if you think this is irrelevant.

We overvalue our own creations, aka the Ikea effect. Ikea produces affordable furniture. The trick: DIY. This keeps labour and manufacturing costs low and the savings are passed on to the customer. Bargain! But there’s another unseen effect to DIY: studies show that people who DIY their Ikea furniture tend to value it more than it’s worth. Because we price in our own labour costs (time and effort) into the finished product. This is why your pricey interior design renovations don’t increase the market value of your house. It’s also maybe why we think our kids are the most gifted? We produced them.
