Abundance vs scarcity mindset

For people, who’ve had bad 20s and who finally found their ground at 29-30, and are trying to keeping at it, do you ever feel like life has challenged you so much already that you want to spend the next decade or so, just being and relaxing?

By bad I mean - mental health issues or continuously choosing wrong people, family trauma healing, et cetera, et cetera. Like you finally feel you’re there in life - personally and professionally at 30.

I often wonder about this that are bad experiences keeping one from adopting an abundance mindset? In the kids context - this could mean not allowing yourself to have that experience because you’re so tired from your challenging years that you don’t want another life altering challenge - even though objectively, you know you’re fully capable of going through it because you’re now a resilient and a thoughtful person.
