Living from Abundance

I am having trouble with the concept of “living from a place of abundance.” Can you explain how to do this and what this concept means? I can understand trying to live as though there is endless opportunity, but when it comes to actually implement it i’m stuck. I am trying to figure out what it would look like to live from a place of abundance but I can’t help thinking “but I don’t have this or that yet” and getting passed what seems impossible. I’m also trying to have thoughts like “there is endless opportunity for success” etc, but it just doesn’t feel REAL.

Could you please explain what living from a place of abundance means and maybe some examples of how to do this in your own life?

Thanks so much!
