grammaticality - "The more..., the less.." type of sentence corrections

The more you think about it, the less likely you will take action.

I feel that sentence sounds a bit awkward, especially the less part. I am not so sure if the sentence is correct, grammatically.

So what's the right way to put it? Or how can I rephrase it?

Answer

Your problem is that we don't say "You will less likely take action", we say "You are less likely to take action" or "It is less likely you will take action". So one of those is what your second clause has to invert:

The more you think about it, the less likely you are to take action.

Or

The more you think about it, the less likely it is you will take action.
