I think one gets insecure when one project's their value on the other person. The person in this respect judges his/ her value based on the actions of other. To minimise insecurity as much as possible, one needs to adopt the attitude of not latching on to the other person looking for validation. Once the person stops latching on to the other person and stops finding validation in the partners actions, i believe insecurity can be minimised. You need to be believe and Remember that you are good, you deserve the bestin terms of people, life, luxury and other materialistic things. It will make you remember that you are, and always will be worth the best regardless of the other persons action.You shape and determine your life.

In terms of dating, you will get beautiful women when you start feeling god on the inside and realise that you deserve beautiful woman and that you are the best thing to happen to them. them looking pretty, 10/10 dasn't give her higher value. she's the same as the most ugliest person so she is - NOT SPECIAL

There are billion people in the world living billion different version of life. You're here on earth just once. It's your decision to live it and respect yourself to let yourself live the best version.

We all may not have the best life and stuff may not be great. But just remembering that you are worth it and all you deserve all the good things ( as long as you put consistent effort in getting them ) you will get them.
