My suggestion is write down a map, starting from "where you want to be" and draw it backwards till you reach the point where you feel is you can start from.
For example a KPOP star would have his/her album/Song in top 10 list. If that is the Goal then make a chart like Song in top 10 <- Many songs creation <- Learn how to produce Good, creative, original music, <- Learn the basics of Music production on Youtube / udemy <- Download A Digital Audio Workstation ( like FLStudio) even only free version to start with <- Get a working Laptop <- etc. so on and so forth.
If you would like I can suggest few ways to start on music production with any prior knowledge or training in Music.
Hope this helps !!
