I feel like this would be more accurate if you said, "Action is the bridge between Goal and Accomplishment." Thought and Result. "Discipline," is a much more skewed, contextual way to say, "action," but the implied meaning is disproven all the time.

It's like when you call someone lucky for their circumstances, and they respond with, "LuCk iS wHeN pRePaReDnEsS mEeTs OpPoRtUnItY," in a judgmental, backhanded sort of way so that they can simultaneously take full credit for their blessings while also blaming you for not having them. You then point out that, "Opportunity is a form of luck, so it'd be more accurate to say, 'Success is when luck meets preparedness.'" Despite agreeing that there success requires effort, that there's more to it than just personal agency and they may have to credit exterior forces or circumstances for success, you get to watch the smug slide right into indignation.

Sometimes they'll double down and say they make their own opportunities, which I point out is actually just more preparedness.
