Some products are “stuck in the middle” (to borrow a term from Michael Porter): they only get a job done slightly better or slightly cheaper. Such a product will likely fail to attract any new customers. This is clearly a poor strategy for a new market entrant, but it may help an incumbent company retain existing customers.
The enthusiasm and positivity that got you in the founder seat can be hurting you. When you’re really focused on your goals, your default reaction to everything else should be “no.” The world needs to work really hard to convince you of something outside your goals. Say “no” and smile. Take pride in it. It took me 10 years to realize that saying “no” and letting opportunities pass can really feel good.
