Ever worked with a mood hoover?
Hell, they make life miserable, don't they?
Are you a mood hoover?
If you are, you need to dig into the pit of yourself and find a way to become solution-focused, rather than objection-focused.

No one likes working with a mood hoover, even if they laugh along with their negativity. Generally, people like to be around positive, successful, future-focused people.
And if you manage a mood hoover, you need to be brave and sit down with them to explain the impact they are having ... and set clear boundaries that give them no choice but to change.
