For the past few years, I've been thinking about products that improve our mental well being, and our overall happiness.
It seems like many of the popular products we use every day actively make us unhappy - e.g. Facebook, Instagram. Others products like Amazon and Uber make our lives more convenient, but not necessarily much happier.
What products out there make you happy and fulfilled?
If we're talking long-term happiness, I guess the closest I can come to is my bicycle, because it keeps me in reasonably good physical shape and being in reasonably good physical shape does increase my overall happiness.
