Is being overconfident bad too?

[Anonymous]

My younger 18 year-old cousin (advanced level in both Judo and Muay Thai... some wrestling too) is obviously stronger and more skilled than the average Jane. She's 5'10 too.

Certain times she steps out late at night. We still tell her to be careful but she's fearless and kind of a tomboyish too. She even mocks at the idea that someone would dare try her or mess with her. No one ever messed with her at school nor other places, but she seems overconfident.

I know she can handle her own but is being overconfident like her bad too?

She's confident that she would be able to knock out or stop any potential rapists, kidnapper or deranged psycho trying to hurt her.
She is confident that most of those crazy psychos go towards weaker victims, not strong, skilled ones.

I guess so, it can easily lead to arrogance and make someone be reckless

With guns, tasers and other weapons (or even chloroform to disable someone)... even the best martial artist would be no match for that.

I heard there are always the exceptional psychos that actually like challenge and go for difficult, harder victims and bring elements of surprise. I think she's being overconfident into thinking no one would dare try her.

Yeah, you can be the strongest human being in the world, but there are still a lot of ways to take you down under certain conditions, so having risky behavior is not advisable, specially being a girl which unfortunately is seen as an easier target by bad people
