You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service and refunds. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. It is hard work, especially on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not. 
Land ownership was also justified according to John Locke. He claimed that because we mix[clarification needed] our labour with the land, we thereby deserve the right to control the use of the land and benefit from the product of that land (but subject to his Lockean proviso of "at least where there is enough, and as good left in common for others.").
If you don’t mind doing other people’s chores, then TaskRabbit is a great option for making money online. Earn extra income by walking your neighbor’s dog or mowing Mr. Smith’s lawn. It might seem like not the most lucrative option, but the top taskers reportedly earn as much as $7000 a month, making this a full-time way to make money online for some.
Given the growth in the sharing economy, your junk can start to pay for itself. For example, if you have some awesome vintage furniture inherited from your grandmother sitting in a storage unit, you can rent this out to photographers for their “styled shoots” which are becoming all the rage. If your furniture is more modern but you still can't bear to get rid of it – perhaps a home stager will be interested.
But most importantly, Sabatier highlights that, while one’s ability to make money is limitless, one’s time is not. There's also a limit to how much you can save, but not to how much money you can make. No one should spend precious years working at a job they dislike or worrying about how to make ends meet. Perhaps the biggest surprise: You need less money to "retire" at age 30 than you do at age 65.
I’m glad I started looking at this when I was in my mid-twenties more closely, but of course, now I wish I knew all this info when I was even younger. So don’t wait, don’t put it off, start right now. And while I may not be able to retire next year or even in five years, I am well on my way to being financially free well before the average retirement age. Let’s do it!

How can I become financially independent fast

My husband retired from the military after 20 years of service last summer at age 38 – his guaranteed income is appx $67k per year for life (tax free and subject to COLA), and he gets an additional $17k the next 4 years under the GI Bill while he’s in school. We have appx $450k invested, no debt, and guaranteed health insurance for life with no monthly premiums, $150 annual deductible and $3k annual catastrophic cap. We have one child, age 5, who will receive free college tuition if she attends a state University in our state of record. We do have appx $25k in a brokerage account for her for addtl college expenses. My husband is considering not working after he finishes school, or working a ‘fun’ part time job. We live in the Midwest, where cost of living is ok (much better than our last duty station in CA!). I work a ‘fun’ part time job bringing in about $1k/mo. Curious on your thoughts as to where this puts us. And, do we figure my husbands ‘pension + benefits’ in our networth?
If you have 20 years left to live and only require $60,000 a year, having $1,200,000 can also be considered enough even if you make zero return. The only problem is that your purchasing power will decline by ~2% a year due to inflation. The other problem is that you don’t know exactly how many years you have left to live. Therefore, it’s always better to have more rather than less.
