A really nice electric guitar, amp, and pedal. Money was tight as a kid for a lot of reasons, my dad did the best he could. However, this meant playing with some equipment that didn’t sound quite right.
Now I have what I always wanted, but have trouble finding the time and energy to play.
Getting some sleep (sober). I’ve learned that the world seems harsher when I’m tired. After a night or two of good sleep, things feel less of an issue.
