Success is truly relative, and varies person to person. It is an opinion within ourselves that holds us to our highest standard. Looking through other people for your version of success is a sure way to create toxic false standards.
Everybody is different, and we all live different lives. To some people success is to have a large family, in a large house, doing the work they love. To others success is the ability to boast exotic cars while throwing parties in exotic houses.
Both versions are ok, neither is right, neither is wrong. The idea of right and wrong is a human complex based off of our concepts of morality. In my personal opinion, success is the ability to be happy as you please, to have the freedom from mental chains we project upon ourselves.
Create goals, have dreams, and work towards them. If we all create goals to achieve, you'll see most goals would be different than each other. Each person would have a different view upon their belief of what a better life is.
