It might be that word has gotten out. There are fewer crazy ideas hitting my desk. Still a lot of deals that I can not invest in. But the viability of these ideas is much stronger. How can I tell? These companies have customers and transactions today. They are selling.

As long as customers keep buying from you and you can make a good profit. You'll be in business. Once that stops then you're in trouble.

Ideas that flame out quickly are fads. Being in a sustainable long term business means meeting a need, not a want.
