If you never fail, you never learn.

Never surround yourself with 'yes men'.

There is always someone who knows more than you.

All three of those sayings sound trite but are very accurate.

I think it takes a confident person to realize they should always be striving to learn from those who are the best in their field.

The "I'm not good enough' gene is there to keep us on our toes. To always question. To always learn.

Not sure any of what I wrote makes sense to your post, but it is what ran through my head when I read it so I thought I would share my thoughts :D

Thanks for such an interesting post!
