The folly of youth is believing that there's always enough time for everything. Youngsters often believe that retirement, or wealth building, is something that comes later in life, and are more preoccupied with the concerns of the now. Unfortunately, this often leads to a cycle of "Oh, I should do that next month," month after month, until before you know it, you're 10 years older and you've missed out on a decade's worth of compounding interest. The first step is to stop procrastinating; saving and investing is scary, but the longer you wait to do it, the fewer advantages you have.
Tim, I know several millionaires, and most of them have done it the old fashioned way, which is working and saving over many years. Some have started their own businesses, some have made wealth through other means such as investments and real estate, and some have done it other ways. Virtually all of the millionaires I know have families (some were married without children, but most had children). I’ve never counted how many millionaires I know, but of the people I know for certain, I would venture to say that I know at least 10-15 of them would qualify under these standards. As for the college education part of it, I’ve never taken a poll to find out how many had degrees and which degree they had, if they had one.
Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. 
I started reading your e-newsletter since I found out about you from Mo Money Podcast. I love this content and I can tell you what my side hustle is that was not mentioned here. I have been a virtual translator via Upwork (freelancing platform). Since I’m originally from Japan, I started offering beginner to intermediate level translation last year. Since then, I have delivered over 6 dozens projects all satisfactorily. I like that each and every project is so unique and it really stimulates my brain and challenge myself to deliver high quality translation services. My hope is that one day when I get pregnant or want to stay home with my babies, I can just do this freelancing job and quit my 9-5 job. Upwork offers so many types of freelancing jobs other than translation, so I recommend to anyone who wants to capitalize their underutilized talents.
The Ego -- Consider the ego as the referee between both the id and the superego. The ego's job is to satisfy the id while also working within the confines of the superego. This isn't the ego in the traditional sense, but rather that component of the mind that acts as the primary driver of the psychic apparatus. Since every person is unique with unique experiences, the ego works differently in each of us.
Just be sure to put a lot of care into your product listings. Everything from the titles you use, to how effective the description is at convincing potential buyers your product is better than the rest, and even taking care to shoot high quality product photos can have a dramatic impact on your sales. I recommend using photo editing tools like Fotor, which gives you the ability to edit your images, create captivating graphic designs and more.
Millionaires are all around us, and many of them are probably not who you would think. This is because they smartly live below their means and save their money rather than showcase it. Of course, it’s easy to live below your means when you have millions, but even if you have far less, getting into the habit of spending minimally now will help you have a lot more later. The trick is adopting a “less is more” mentality and sticking with it, even when your income and net worth increase in the future.
