Neither perseverance nor self-reliance are particular points of emphasis in my tradition. In some respects, they'd be considered vices. Why?
Perseverance shouldn't be needed when one is attuned to the proper course of one's life path. One simply flows in the direction one is meant to flow in. Too often, perseverance is spitting into the wind when one could simply swallow, wading upstream when one could flow down the river, or building walls when one could simply let others in. Humans are often very bad at accepting change in spite of it being a fundamental constant of our world. Focus not on perseverance, but on letting go, going with the flow. Knowing limits exist and accepting them.
Self-reliance is simply impossible. Everything we are and do rests upon and depends upon countless human and greater-than-human others. Why are so many humans so scared of the interdependent weave of existence? It's just strange to me. Does Mother Sky not provide Air for you to breathe? Does Mother Earth not provide food for you to eat? Does Mother Sun not warm your skin and let you see? Perhaps modern, domesticated humans have become too blind to the gifts of the gods when we pluck them off of shelves in some store cut off from the sun and the rain and the wind. Or when we slap a dollar value on everything and commodify it. Just a few moments stopping to think about it though and it is impossible to not recognize our interdependency on others. There is no self-reliance. We all rely on the world (the gods) to exist.
