Zen and the Art of Motorcycle Maintenance is probably a given, but wow - what a read!
Personally I love any Steinbeck, and in East of Eden, I think his exploration of Timshel resonates with a DIY/ craftsman's attitude.
Ruskin's essay on The Nature of Gothic is another one that really captures the humanity in creativity.
Thoreau's Walden is a given, but his essay on Civil Disobedience is one that also resonates with a pre-industrial approach to life.
Wordsworth's The Prelude is one of the greatest poems ever written and focuses a lot on creating a life of little loves and joys.
Gray's Elegy in a Country Churchyard is another great poem (and much quicker to read) and is a reminder that a life of humble joys and not chasing wealth or such nonsense is the better path.
Seneca's On the Shortness of Life is a good reminder for what our relationship with time could/should be.
Camus' Myth of Sisyphus should be compulsory reading in my mind - one must imagine Sisyphus happy after all
Boethius' Consolation of Philosophy influenced writers and thinkers for thousands of years after him, and I think there's a lot in there of value.
(Sorry for the giant list - English tutor and obsessive reader here and I see a lot of crossover with these books and why people choose handtools over power tools)
