Whenever I buy clothes they always end up getting holes quickly, I burn through socks fast, my bags keep breaking, my phones magically shit themselves and my chargers melt. I'm sick of everything being a wear part and I'm wondering where people get things that last.

I gained like 10% battery per day by uninstalling a few of them.
