The only real, safe way: Get a good job, work hard at that job, get promoted to the top, live within your means and save everything you can. From there you take care of your assists and put funds wherever you think offers the best lowest risk to reward ratio. It is as simple as that. 
Wealth: everyone wants it, but few people actually know what they need to do in order to get it. Becoming rich takes a combination of luck, skill, and patience. You have to be at least a little lucky; you build on that luck with your skillful decisions, and then you continue weathering the storm as your wealth grows. There's no reason to lie to you: getting rich isn't easy, but with a little bit of perseverance and the right information, it's definitely possible.

well adding to this, its more of like have you given your chance to even open doors to make more then one sale.
Meaning have you created a plateform or something that will escalate your leverage time to break a sale even while you sleep. I mean theres also the misconception too, where daytraders get that 1 hit win and they stop trading but they made a ton of money.
