Amplification is like using a sledge-hammer to swat a fly. There are easier ways to do it. People tend to amplify for two reasons. Firstly, they over-prepare for things because they want to avoid possible outcomes they see as unacceptable. Over-preparing for a speech, or continually re-packing for a trip fall into this category. While it is possible that one more run-through of the speech will lead to an improved presentation, or that one more re-pack will bring to light something that has been forgotten, the law of diminishing returns make these outcomes less and less likely.
Repetition, as seen in the above examples, is more likely when it's difficult to tell when the goal has been attained. How do you know when you are rich enough, or famous enough, or truly loved by your partner? In the latter case, no evidence may be sufficient so looking for more is useless. This is the time to learn to trust that you are lovable..
In the case of wealth, fame or power, achievement of a goal may lead to setting a higher goal because you now compare yourself to different people. The question to ask yourself is if you want to spend your life chasing an ever-expanding goal of wealth, power or fame, or if there are other ways you prefer to spend your limited time on earth. Is "I am the richest (most famous...most powerful...most...?) person on earth" going to be the thought that sustains you on your death-bed, or are there other things you might achieve that would have more meaning?
