Many moons ago I heard these lines:<p><pre><code> - "Just when you think you're the smartest, know that there's someone out there that's just as smart and probably ten times smarter!"
- "There's no such thing as an expert"
</code></pre>
They keep me humble :)
Loss of morale is what undermines the persistant efforts needed to make great things happen.<p>Having a healthy ego and doing objectively great things to feel good is not in itself 'toxicity' that must be 'killed'.
