Hello, the steemSTEM tag is meant to be used for Science, Technology, Engineering, Mathematics posts. From my view, I don't think this post is related to the topics in any way. You could get into trouble with steemcleaners.
stemSTEM is actually a community you can join and you'll definitely get someone to mentor you and teach you how to craft a good steemstem post. You can consider joining us on discord. You might also choose to contact me. Join steemSTEM here
