Seriously though. Hurraaaaay you met the bare minimum.
Sure, being nice is important. Being nice is underrated. Assholes are everywhere. But don't act like it's the only reason you should be ahead of the pack.
Nice is never the first attribute listed when someone is looking for client, peer or partner.
What do you bring to the table? Who are you going to be in 10 years? How does your brain tickle their brain?
If that sounds 'shallow' or 'selfish', you need to stop making excuses for rejection. If you are so smart, funny, talented, or ambitious, what are you doing to demonstrate it, personally and professionally?
If all you can do is list faults that you don't have then you might as well drop out of the race.
Girls don't fall for jerks because they have nothing to offer. You don't get passed on promotions for people that are just nicer than you are. It's always the perfect time to show up.
Saying you are a nice guy is like your cab driver expecting praise for not getting in an accident. It's appreciated....but it's also expected.
