What is the Real estate Investing Skill that most newbies overlook?

I noticed many new investors who lack experience lack patience and some think that certain houses based on the rough looking pictures are not good deals when I try to teach them that ugly pictures are okay and that is an easy fix. We can make every ugly house look nice and upscale. Many people can not visualize how a house could look like after its been fully remodeled and or fixed. Also, some newer investors think because a house does not need a lot of work but is located in an area where I would not want to buy, they think buyers still would buy this house because the house itself is beautiful. I learned that no matter how nice the house is, the area and location and price is all that matters for future buyers so be careful there! I always recommend to have new investors partner up with other more experienced investors so they can avoid some costly mistakes, good luck!
