Are you one of the legions of men who suffer from “Nice Guy Syndrome” ? – a set of personality, attitude, and behavioral traits described by Dr. Robert Glover, author of No More Mr. Nice Guy.

Nice Guy
Nice Guys take a passive approach to life and relationships. Instead of standing up for themselves, they let others walk all over them. They’re pushovers and perennial People Pleasers. Nice Guys have a hard time saying no to requests — even unreasonable ones. They’re considerate to a fault. When they want or need something, they’re afraid to ask for it because they don’t want to inconvenience others. Nice Guys also avoid conflict like the plague. They’d rather get along than get ahead.
At first blush, Nice Guys seem like saints. They appear generous, flexible, and extremely polite. But if you scratch beneath the surface, you’ll often find a helpless, anxious, and resentful core. Nice Guys are often filled with anxiety because their self-worth depends on the approval of others and getting everyone to like them. They waste a lot of time trying to figure out how to say no to people and even then, often end up still saying yes, because they can’t go through with it. They don’t feel they can go after their true desires, because they’re locked into doing what others say they should do.
Because “go with the flow” is their default approach to life, Nice Guys have little control over their lives and consequently feel helpless, shiftless, and stuck. They’re also typically resentful and vindictive because their unspoken needs aren’t being met and they feel like others are always taking advantage of them – even though they’re the ones who allow it to happen.
In worst-case scenarios, the Nice Guy’s pent-up resentment from being pushed around will result in unexpected outbursts of anger and violence. He’s a volcano waiting to erupt.
So what’s a Nice Guy to do? How can he regain some control over his life and quit being such a pushover?
Some Nice Guys think the solution is to swing to the other extreme and go from being passive to aggressive. Instead of meekly submitting, they feel like they have to dominate in every situation. They seek to get their way in everything, no matter what.
Aggressiveness, while definitely appropriate in some instances, isn’t a very productive communication style in most cases. In fact, using a persistent, aggressive communication style can often backfire by creating resentment and passive-aggressive behavior in the very people you’re trying to control.
Instead of passivity and aggressiveness, the best approach lies somewhere between the two. The sweet spot for communication and behavior is called assertiveness.
