Where did you learn partitioning? And do you need a guide everytime you install a distro?

I have been using linux about 4 years now and in that time i’ve done a bunch of installs. Lately i’ve been setting up luks and lvm, but each time i install a distro ive set up bodhi and nixos with this setup but the issue i have is that each time ive done it i’ve had to follow a guide....
