How much is your income and savings? From your savings annually, you should be able to estimate whether you can achieve $10m in your working lifetime.

To hit $10m by 55, you have to grow your net worth by $410k each year. Are you achieving that now? It is good to aim high, but don't stress over it. $8m is also good enough.

With $8m, we are literally having a perpetual money making machine churning out $250k - $300k passive income annually while we relax one corner. It is a happy problem of deciding what to do each month with the money coming in. We usually end up reinvesting the money.
