As I’ve grown into a man, and realised the position of the head of the family, I realised that I have to protect.

It’s easy when somebody is aggressive or disrespectful to me - I can retaliate instantly so they never forget it.

But it’s different when it comes to my family etc. Any sources for a impenetrable defence to secure a family mentally, physically, financially and spiritually?

It’s not something I need to do but it’s something I want to be able to do and know how to do. Please link sources.
