Imagine planting a seed and then digging it up every few days to see if it has grown.
You would never get to see the tree that bears fruit. Or you would significantly hamper its progress and growth. You might end up with the fully-fledged tree eventually, but it would take much longer than it might have otherwise, and the constant disturbance to its growth would probably result in a weak, sickly plant that only makes you feel discouraged when you compare it to the beautiful, flourishing tree you saw in your mind’s eye when the seed was first planted.
No. You wouldn’t open your eyes to see a new trophy appear on the desk before you, or something like that.
But if it worked exceptionally well, something might occur along these lines: the judges of the competition discover that the first place winner cheated or broke some obscure rule of the competition, therefore they are retroactively disqualified and the first place prize defaults to the next runner-up, i.e. you.
Even if nothing manifested from your revision, you would still gain the benefit of aligning your mindset with that of a first-place winner, feel the associated emotions of joy and gratitude, and attract those outcomes to you in future.
