Has anyone tried Successinsider for working through limiting beliefs?

Lately I’ve been noticing how often my own thoughts hold me back from going after bigger goals, and it’s been pretty frustrating. I came across Successinsider, and they talk a lot about habits, mindset, and breaking limiting beliefs using different frameworks.

Before I spend too much time going down that rabbit hole, I wanted to ask here. Has anyone actually used their content or programs to work through mental blocks? Did it help in a practical way, or was it mostly surface-level motivation?
