thank you!! at the moment i do not do any tutorials, im not certain how to go about making one, as half the time i don't use a lot of guides myself, however maybe in the future when i have the time I'll figure out a way to form or categorize or illustrate the thought process and share the basics that i use for almost everything :) but genuinely for now my only advice is to make a routine out of art instead of making it inspiration/motivation based (if you cant do something creative then do studies to your hand and eyes can memorize), challenge yourself with different stuff (machines, shoes, cities - drawing stuff that is a pain, its different for everyone) allow yourself to play as in draw stuff that is very niche and catering only to you, passion projects of sorts because that will help you push yourself, and ofc eat and rest appropriately because a tired artist will always edge closer to burn out, which is never good.
i hope this helped at least a little. thank you for the question <3
