How to have more than just barely enough?

Why do I only ever have enough to pay the minimums on my debt? My result I want is to pay it all off and to have more money than I need every month. I think I believe it and I’m working but then it’s like another bill comes or I can’t get out of the debt of my past thinking. I can’t seem to get traction to get ahead. Of course I want to make much more but then I work really hard and can’t get ahead of this debt. Thank you.
