making a bundle

[keannu]

Does this "bundle" mean "package" or "a very big amount"? I think the latter.

36)Making $1 million in one year, but nothing in the preceding nine, does not bring the same pleasure as having the total evenly distributed over the same period, that is, $100,000 every year for ten years in a row. The same applies to the inverse order ―making a bundle the first year, then nothing for the remaining period. Somehow, your pleasure system will be saturated rather quickly. As a matter of fact, your happiness depends far more on the number of instances of positive feelings, what psychologists call “positive affect,”

Yes, a bundle of money is a lot.
