Do nice guys always finish last?
Some do. I know a few who have, and plenty who have come first. I also know not-nice people who’ve done well and many who’ve failed.
That’s the trouble with cliches. They rest on a few examples but rarely on solid evidence.
There’s also the issue of definition. What’s ‘nice’? Is it polite and supportive, or just people-pleasing? What about ‘humility’? Does it mean humble and meek, or being comfortable with who you are?
