Yes, but it doesn't take millions.
Tell me, what would you consider successful? There have been quite a few geniuses throughout history who make great scientific contributions and change the world, but wind up dead broke? Would you consider them failures because they didnt have money or cars or big houses?
Yet, their ideas are worth more than you will probably ever be or make or contribute to this world. But you probably think you are more successful than them.
You clearly stated that money equals success, so I guess they wouldnt be successful?
