On the other hand, you don't know how much time you have. You can estimate based on family history and the average lifespan for someone of your ethnicity and income level but that's not necessarily accurate.
Furthermore the cost of all the opportunities lost is always unknown and can be greater than whatever monetary amount you have.
Time is the most valuable resource we have. If you can't invest time, you can't earn money at all, but money may not buy you more time.
