Having a cold shower at the end is probably number 1 if I made a list of things I do right in life that most people don’t do. I feel so clean and comfortable for ages afterwards, no matter if I’m in my house or the middle of the forest, summer or winter. Best thing my dad ever taught me. (I mean he’s still alive, so technically ‘best so far’, but I’m not holding my breath).
A lot of old hard rock and metal with power chords is easy to play a simplified version of. I think Metallica - ‘For whom the bell tolls’ and ‘Enter Sandman’ were probably the first things I learnt. You can learn enough to have fun playing a riff like that even if you struggle to get your hand into position to do proper 6-string chords.
