I'm not sure when being called "nice" became a bad word (especially if you're 30 or under). But that's the case in 2014.
I think the media is partly to blame. For example, Reality T.V has helped to turn "being nice" into something almost profane.
For example, notice how the meaner or bitchier people get the more airtime, fame, interviews and even spin-off shows they get. The "nicer" ones usually get less airtime, ignored and even cut from the shows.
Let's face it, "mean, bitchy and arrogant" sells and is slowly becoming the norm. Yes, being nice is not for wimps.
I personally fall between the two schools of thought. Yes, being nice is not for wimps - but it's still necessary and beneficial to your health. Read List of Health Benefits of Being Nice
Now it requires specific survival skills to avoid the negative consequences of being called nice. For instance, encouraging others to abuse, manipulate or control you.
Here's a few tips that worked for me:
1. Don't tempt people to take your kindness for weakness. Look confident, competent and in control.
2. Avoid people who can't, don't or won't appreciate you.
3. Stop worrying about what other people think of you. Stop people pleasing.
These are my top 3. Do you have any "nice person" survival tips?
