A key piece of advice I once received in my career is this, and I think it applies in any industry, at any level:

“Give solutions, not problems”

In other words no matter what your problem is, whether it is with a product or service your company has, whether it is with a co-worker, your boss, whatever, instead of just complaining about it come to the table prepared with ways to correct your problem. In fact you should come prepared with at minimum 2 solutions.

Anyone can complain, it adds next to zero value to the situation. Bring a solution, and you will gain respect from your peers and better chance of resolution.
