Stop saying “yes” when you actually mean “no.”
The two-letter word “no” can be quite intimidating. I get it. But the more we incorporate it into our vocabulary, the more natural it will feel when rolling off our tongue. So if you’re not pumped up with excitement with each new opportunity or request that comes your way, say “no.” (That is, unless it’s your boss.) Trust me – it might feel weird at first, but your happiness level will improve in the long run.
