Strong important !!

Hello everyone Who can give me some advice? Anyway, I'm a guy. And to be honest, I considered myself a complex guy. Because I consider myself weaker than other guys. I am not 18 years old. I've never practiced martial arts. That's why I feel weak in the men's team. What should I do about it? Isn't it too late to start practicing martial arts?
I'll say this: no one bullies me, I'm considered smart, but I'm afraid that in some conflict I won't be able to properly stand up for myself and my loved ones.

It's not too late, anybody can practice martial arts. Just don't delay it unnecessarily. You know what you need to do, all you need is to do it. Embody the full spectrum of humanity and masculinity. Be intelligent, educated, and strong and capable. Not just a nerd or a neanderthal. Then respect will come from all sides, within amd without.
