I am not sure about the meaning of a sentence... Could any native speaker help me? :)
"Try some small thing that they would be reluctant to do under normal circumstances and gradually experience, hopefully, no horrible thing happen when they push through and carry on."

Question

Answer

In other words:

"Try something new they wouldn't normally do and slowly experience it. Hopefully, nothing will happen as they get through it and carry on."

Hopefully that helps a little.
