A big part of this could just be mild burn out. I find that if I take a long vacation, sooner or later I get bored and get right back to being curious and working on building or learning something. Having said that, I have a harder time finding meaning in side projects now that I'm older. There's a bit of nihilism in me now, kinda like the koa “If a tree falls in a forest and no one is around to hear it, does it make a sound?" If I work on a side project and no one uses it, does it even matter? Learning for the sake of learning has become near meaningless to me.
