Yes! This is something I wish I better understood when I was first starting as an entrepreneur. I assumed the best people ot get advice from were the rich, successful entrepreneurs who'd built "famous" companies.
Turns out, they tend to be more like what you've described. They tend to mentor young entrepreneurs because it makes them feel good (I heard the phrase "giving back to the community" a lot), but their advice is often -- to borrow your phrase -- lazy.
