Looking for Recommendations

Hey guys! I've ran out of stuff to read so I'm trying to look for manhwa recommendations about a specific genre (and I most likely have read them already but want to reread them). I think it falls under fantasy genre in general, but it doesn't have to be fantasy. I want to read a manhwa that revolves around being/trying to be the best in their profession or field of work, such as being the best chef, being the best architect, being the best doctor, being the best idol, being the best farmer, etc. Similar manhwas would be like Spirit Farmer, Strongest Florist, Leveling Up! By Only Eating, God of Cooking, etc.

Thanks for the recommendations in advance :)
