I used to just try to better my own skills and compete against myself. There is a balance in life. There are some things I will never be able to do and many I can. Telling someone they are always better than everybody else is a lie. Telling someone they are always a loser and worthless is also a lie. Just tell the truth.
Yes. A true sense of high value in yourself is not a comparative thing with others. It is a sense of intrinsic worth and love because you are you. It’s a sense of unconditional acceptance and belief in you. Comparisons with others are often signs of low self esteem.
