I think I would define success as living a happy and meaningful life. It's really easy to get wrapped up in matters that are ultimately trivial - money, status, material objects, hollow relationships, etc. A lot of time can be wasted doing things that ultimately don't make us happy, but we think it will/should. I've recently realized that I want to do something that matters and I want to have relationships that are important, carry value and are meaningful. Finding love and embracing it.
