Amen!
It doesn’t matter what developer you are, this is a general “developer commandment” I believe in.
A lot of times too, especially helping on the Internet, you might try and help someone, only to learn, you aren’t quite right yourself. So you also end up learning too. I think, as a developer, being humble in knowing that I don’t know everything, is also important. It is actually another commandment.
“Thou shall always be humble and never think thy knowledge is all encompassing!”
The other commandment from Bruno could be
“Thou shall always help the lesser knowing developer”.
