is it important to become better?

is it important to become a better person not specifically for you but in your eyes should everyone be trying to become a better person? I used to be obsessed over taking steps to become better, do better change my personality traits , but in the end it always not only goes back to the way it was but usually becomes worse, i want to try different method of changing my personality but i dont know what to do so in life right now i am just trying to settle down with the fact that im not doing anything to change and become better because doing a method that dosent work and chastising yourself for it not working is worse then not doing anything. so i think that it dose not matter whether you improve yourself or not in life even trying to improve dosent matter all that matters is that your enjoying life.
