"Your value does not decrease based on someone's inability to see your worth."
Self appreciation and respect is the most important aspect of life. If you do not appreciate yourself and value your worth, how do you expect others to? Life is short for you to maintain toxic relationships. In order to flourish yours, you need to work on yourself first.
I truly believe that self worth is not about measuring yourself based on external actions. It's more about valuing your inherent worth as a person, meaning, it is not about what you do, but it's more on who you are. The problem with the society today is that, we tend to focus on measuring ourselves against others, and pay little attention to our intrinsic value.
As a student, I always compare myself against others. I want to be better than anyone to earn recognition. I want to feel special. But the truth is, there is going to be someone who is much smarter, richer, attractive or successful. Constantly comparing ourselves to others is like fighting a losing battle. And even if we do manage to get one golden moment, we can't hold on to it forever.
How others see you is irrelevant if you do not appreciate your own self. Every person is special. You just have to be willing to accept your flaws and focus on constantly developing yourself in becoming a worthwile person even further. Learn to show respect for yourself. When everything else fails you, you will always have yourself to fall back on.
Remember, love yourself and take pride in who you are and what you have to offer!
