I'd rather have 85%+ on big AND small accounts. And that's what I've got, and that's what I earn... because I paid my dues and I have the education, resources, and training that I need to serve my clients. I've been doing this for over 10 years, so I'm not "new to the business".
Then good for you, I've already learn from someone with 20-30 years experience that I am more comfortable with learning that have been in the business for that amount if time.
This is a business and a place to learn. So you can advise but don't force your logic down someone's throat.
