There are two people out there, both authors, that I consider being on two sides of the personal finance/ business finance spectrum. One is Dave Ramsey, the person in the first video, and the other person is Robert Kiyosaki, the person in the second video. Ramsey is focused on eliminated debt all together and living life on what you actually earn. Kiyosaki is very much an advocate of using OPM (Other People's Money) to expedite your growth of wealth.
I don't think either one of these options is completely wrong, however, I do think that one of these could be completely wrong for you. Anyone can do Ramsey's method, you don't have as many toys and live within your means, but you eliminate a problems that causes more fights and stress than almost any other problem in the world- money problems. With Kiyosaki, you can quickly raise up to the top, but you start gambling with OPM instead of intelligently investing you will crash very hard and have more stress and problems than anyone cares to have. Clearly, if you have single and have no one relying on you, but yourself than it might make some sense to take a risk and use OPM to start a business or invest in some properties. But if you have a family the prudent thing to do is steer more toward Ramsey's methods. I think that if you use your head and find yourself wanting a little bit of risk, but not so much you may end up in a gutter, you can always find a place half way in between these two men... that's where I would place a person like Ramit Sethi. I am not here to decide what personal finance path you should take, I just give the information.
Both men have a lot of other ideas outside of debt and I think both men have genius ideas. I have read everything both of them have written and have thoroughly enjoyed all books.
Here are the videos:
