13 Things Mentally Strong People Don't Do_ Take Back Your Power, Embrace Change, Face Your Fears, and Train Your Brain for Happiness and Success ( PDFDrive )

You spend a lot of time complaining about people and circumstances that
you don’t like.
You often complain about all the things you “have to” do in life.
You go to great lengths to avoid uncomfortable emotions, like
embarrassment or sadness.
You have difficulty setting boundaries, but then feel resentful toward people
who take up your time and energy.
You hold a grudge when someone offends you or hurts you.
Can you see yourself in any of the above examples? Retaining your power is
about being confident in who you are and the choices you make, despite the
people around you and the circumstances you’re in.
WHY WE GIVE AWAY OUR POWER
Lauren was clear that she really wanted to be a nice person, and she thought that
being a good wife meant tolerating her mother-in-law at all costs. She felt it
would be disrespectful to ask her mother-in-law not to come over and she was
hesitant to speak up when her feelings were hurt. She’d been raised to “turn the
other cheek” when someone treated her poorly. But with help, she was able to
see that setting healthy boundaries wasn’t being mean or disrespectful. Instead,
setting limits on what was allowed in her own home was healthy for her family
and less taxing on her mental strength.
Anytime you don’t set healthy emotional and physical boundaries for yourself,
you risk giving away your power to other people. Perhaps you don’t dare say no
when your neighbor asks for a favor. Or maybe you dread receiving a phone call
from a friend who constantly complains, but you continue to pick up on the first
ring. Each time you avoid saying no to something you really don’t want, you
give away your power. If you don’t make any attempt to get your needs met,
you’ll give people permission to take things away from you.
