When I was a junior, mid, and starting senior level developer, I was so focused on getting ahead, and I would’ve listened intently to this.

The reality is though that most managers and principal or higher devs are great with you taking on responsibility if you’re ready for it, and making mistakes and learning is often fine, but when you stop respecting those with more experience and start working around them, they’re not going to be happy.

My advice: take on responsibilities and do the work, but always respect others. You will never regret giving someone enough respect. If you have a heart or a brain, you will almost certainly regret not treating someone with respect; it will haunt you, even if you one day apologize to them.
