Massive action to counter it?

Quick clarifying question: In the March homework #3, we are to think of a counter thought to practice and a massive action to go with it. Is the action supposed to be something we do right away? Or something we do in the future?

Here are some examples of the conflicting thoughts I am having:
“It’s impossible”
“You’re being too ambitious.”
“$45k is a lot of money.”
“People don’t do that.”

I can think of counter thoughts for them, but not real massive actions, other than practicing the new counter thoughts?
