Great interview on Q just now with Matthew Crawford on his book
Shop Class as Soul Craft: An Inquiry into the value of Work.

A former white collar worker, Crawford explained how he found salvation through returning to his first love: motorcycle repair. He explains that working with one's hands and fixing mechanical objects is immensely gratifying + grounding because it's a genuinely rational activity in an increasingly irrational and abstract world.
I agree.

Now, excuse me while I go hammer something into the wall.
