Just like in the title. Imagine you are a mentor and can share only one advice with your mentee. Would would it be? ^^

PS: This post isn't directed only to super experienced developers like seniors, principals, or maybe team leads etc, but also juniors and people who have just started.

I hope this will create some nice healthy conversations and open closed doors, that everyone of us have, no matter of how many years behind we have.

Being a developer is a lot about having the right mindset, so I'm really curious what advices you will give :D
