The whole exercise of going through thoughts to change behaviour culminates at this important point – invalid thoughts should, and can be replaced. It’s not easy at all. But that’s the whole drive of CBT.

Thought replacement naturally results in behavioural change. For example, if there’s no need to be frustrated anymore, there won’t be a reaction out of frustration.

And finally, practice makes perfect. Actively changing thoughts is a lifelong process, and only gets easier with time.
