I however am very normal. Trust me.
From his prospective I understand, you are engaged in what is considered an extreme sport, the first thing most bosses want in this industry is simply reliability.I'm going to try and give him some notice, but I don't how well that'll go down cause I'll most likely have to take Monday night off due to my arm, he won't be happy due to it being a long weekend and all.
From your view, you are doing the right thing - give him some notice (last job like this I offered to stay on until they had a replacement), thank him for employing you (especially if he's a megalomaniac), leave on good terms, reflect on what you have learnt and find a job that suits your lifestyle or one that you enjoy more. There is no benefit in burning bridges, short term fun for potentially long term woe.
I was in various labour jobs for about 15 years and had only one or two bosses that I wouldn't run down at night if I could get away with it, learning to manage bosses is a skill well worth having to have learned.
