Are you in vanilla minecraft?
If so the best strategy is to be on the edge of two of the edges of blocks and dig down so that even if you run into lava you won’t fall down. When you’re at the bottom level dig 2 high by one width tunnels with two not mined blocks inbetween going outwards. When you run into lava just go back and dump your crap in chests. Then go up two levels until you’ve mined out everything.
Back when I still played vanilla I got bored cause I built a 1:1 scale replica of Okami and didn’t know what else to build.
I’ve gotten bored of feed the beast cause I’ve pretty much done everything imaginable and done everything.
Oh also personally I think very tall narrow towers are the best design for buildings, cause all you need is one torch for each level so you don’t have to waste resources.
