A little knowledge is a dangerous thing A lot of knowledge without wisdom is more dangerous. (Knowledge and Wisdom are not the same)
Though Krunchy may come to mind, this is intended more for newbies newer than I am and I'm definitely a newbie.
Acquiring power tools and only knowing how to turn them on to rip, cross cut, route or bore is potentially dangerous. Knowing how to set them up properly and use them correctly reduces the risk of appendage loss. Knowing which to use and when - that starts getting into the wisdom part of this woodworking thing.
Knowledge, applied without wisdom, is what's going to get one in trouble. "I will because I can." is often the first step to grief. While gaining knowledge, try including gaining some wisdom.
