Oh fun! Spun rod bearings!

Education is always expensive, regardless of the field that you are in. I'm kicking myself for buying 800cc injectors because now I want to go E85. That's life and it doesn't end until you do.

There isn't enough time to know everything, so eventually you accept human limitations and strive to be the best at what you specialize in. The rich are people that specialized in something valuable and the poor are people that didn't have a plan.

Nothing wrong with wasting money on hobbies, if you are conscious that that is what you are doing.
