> Don't propose solutions, that you will have to own (at least partly).

I find that if I propose anything at all ever I immediately become the responsible party for it and forced to own that no matter what it was. Which has lead to me not wanting to propose anything anymore. If I expose that we have a problem with X, I am then the one tasked with solving it no matter how much is already on my plate. So now I try not to see things that aren't going to immediately put us all out of a job.
