It isn't about a comfortable lifestyle but about a fulfilling and rich life. Depends on the person what their definition of that is: some might just want to spend quality time with family and friends, others might want to have a much wider impact.
Its amazing the interesting opportunities and access that big money can open up (while I don't have it I know what it can do), you can do the same with a $10M but on a much smaller scale and you will hit brick walls a lot sooner and it can get very frustrating.
Either way, the time to work your butt off is now, you can take it easy when taxes go up in a couple of years and killing yourself for that extra $ won't be worth it.
