Totes agree! Check this out, I work this a while ago but it makes sense with what you're saying.
"In Adam Grant’s Give and Take, he concludes that “givers”, or people who help others with no strings attached, consistently outperform selfish coworkers or “takers.”
A study conducted at a sales agency in North Carolina found givers produced 50% more sales revenue than takers, as long as their actions were well-intended.
It could be a karma thing, but I think givers win because the opposite philosophy, a spiteful taker, is emotionally exhausting.
How could anyone get any work done if you sit around all day plotting and brooding like Voldemort?"
