This will show u how to level up faster than other people

First Step is to make a texturepack slowly and update it every day with new features
and keep that up for a few weeks post as many submissions as you can and advertise to people on what u made
make skins for people on request no just randomly you wont level up fast

make projects to get a decent amount of people make a server/mod for most

this is how i leveled up so fast to level 22 i have 1 server 18 skins 2 texturepacks and 6 projects
