Say No
A lot of us are selfless people who would do anything to please others. But sometimes you just need to learn to say No.
If you’ve said Yes all your life to your friends, for example, helping them out with advice and generally always being there for them, it’s time that you said No at least once in your life. Saying No is really empowering and definitely makes you feel happier. It reminds you that your time is your time and not someone else’s.
