Can you be truly successful without money? Without money to provide richly for your kids and buy them things you never had? Have your say here!
Depends largely upon what you consider a success.
Money is certainly a "force multiplier" of efforts to be a success. What I could do with the money I see fools waste every day would be absolutely amazing.
But, by that same token, money doesn't guarantee success. Every year, companies that were started with millions of investor funds go bankrupt and fail while you have other companies like the following:
Amazon: Group of highschool students who started working from a garage and a few storage units.
Google: College students who took the idea of using traffic data to prioritize search engine results.
Apple: Started in a garage.
Cysco: Husband and Wife in college started creating networking hardware in their dormitory (I believe they were married at the time).
Now - it would be erroneous to say that these people did what they did without money, as it was the initial success of their ideas that attracted investors to give them the resources to scale up their operations - but they would have been successful even without those investors... just not as 'explosively' successful.
There are countless examples of stuff like that stretching back to the first vacuum tube amplifier and even further into the history of our nation.
