Dear those who feel as if they are never good enough,
First I want to start this by saying you are good enough. You are beautiful. You are intelligent. You have the potential to be whatever you want to become in life.
I know, at times, it's difficult to live up to the standards that others, or you, set. Sometimes, those standards are the problem. Striving for perfection isn't wrong, but expecting that one day you will get there is. Perfection does not exist and it never will. Perfection is in the eye of the beholder. Perfection, to one person, may not be perfection to another. If you strive to be perfect in everyones eyes you will feel as if you only do wrong and that is because in a way you are. Its impossible to always make everyone happy. Sometimes, you need to make yourself happy and strive to be the version of perfection you have.
Always remember that the only opinion that really should matter is your own. You need to become the person that you want to be. Sometimes, that may be difficult; sometimes, we are the most difficult on ourselves. When you find yourself being hard on yourself you need to take a step back and think to yourself, do you like the person you have become. If the answer is yes, that is all that should matter.
Throughout life you are going to lose people. You are going to let people down and you're going to have to understand that it happens. It's natural to let some people down and, sometimes, it isn't your fault. There is no reason to stress yourself out because you let a couple people down when in your heart you know that you tried your best at everything. If you tried you best, that's all that matters. If you put your heart and soul into every word, every movement, every amount of effort, then you did your job.
So just remember in life there will be times when you feel as if no matter what you do you can't please everyone. That's because you can't. I know that's not the most helpful but its true. In life you won't be able to make everyone happy and that is something you are going to have to get used to.
Just remember, in the end the only person you need to please in life is yourself. If you are proud of yourself and everything you have done that is all that matters.
Advice from someone who is learning, just like you: Keep doing what you're doing and stop stressing about things you can't change in life.
