How I Earned $5,071.38 in Side Income Last Month [March 2019 Income Report]

March 2019 Income Report - 99signalsWelcome to my March 2019 income report. Last month, I was able to generate side income earnings of $5,071.38, with a net profit of $4,749.28.

The total month-on-month revenue was up by 15.65% and the profits were up by 14.54%. Overall, it was a great month in terms of affiliate revenue, but not so great in terms of fresh content created.

As always, before I reveal my side income earnings, let’s take a look at some of the key highlights of the month.

Content Creation

Not a whole lot of fresh content that I worked on last month. As I mentioned at the start of this report, it wasn’t a great month in terms of new content created. That said, the published articles are all long-form and in each case, there was an attempt to cover the subject matter in as much detail as possible.

Below are all the blog posts published in March 2019:

2019 Goodreads Reading Challenge

Goodreads 2019 Reading Challenge

The Challenge: Like last year, I’ve taken up a Goodreads reading challenge in 2019 and the challenge is once again the same — to finish reading 100 books by the end of 2019; 25 of which to be business books.

Here are the three business books I read in March 2019:

Bad Blood is undoubtedly one of the best books I’ve ever read. It’s unputdownable. In the book, John Carreyrou, a Pulitzer prize-winning reporter from Wall Street Journal, tells the story of the rise and fall of Theranos, a healthcare startup founded by the enigmatic Elizabeth Holmes who claimed to have revolutionized the healthcare industry with a device that would make blood tests significantly faster and easier. The only problem? The technology didn’t work. For many years, Holmes deceived and misled investors and business partners before her fraudulent practices were finally exposed.

Incidentally, Carreyrou was the first reporter to investigate Theranos and its astonishing claims. In 2015, Wall Street Journal published several articles, questioning Theranos’ claims and techniques. In 2015, Theranos was valued at over $9 billion. A few months after Carreyrou’s article was published on WSJ, Theranos’ value plummeted to zero. The book is an absolute page-turner and serves as a cautionary tale to young entrepreneurs all over the world.

Bad Blood: Secrets and Lies in a Silicon Valley Startup by John Carreyrou

iWoz is an interesting account of Steve Wozniack’s life before and after he co-founded Apple with Steve Jobs. Woz, as he’s affectionately called, is often called the “Other Steve” and although he was instrumental to Apple’s success, especially in the early years, his legacy has largely been overshadowed by Steve Jobs. So it was really interesting to read about his escapades in his autobiography and get a different perspective into the fascinating journey of Apple.


Of all the books I’ve read in 2019, the concept explained in the book Mindset by Dr. Carol S. Dweck will stay with me the longest. In short, the book delves deeper into two mindsets that dominate our lives — fixed mindset and growth mindset. The fixed mindset limits our learning and makes us more concerned about how we’ll be judged by others. The growth mindset, on the other hand, is concerned with improving. Failure is not an indication of our potential. It’s a stepping stone to success and greater opportunities. While we are all a mixture of fixed and growth mindsets, it’s only when we truly embrace our growth mindset that we are empowered to take up new challenges, learn new things, and to confront obstacles.

Quotes I’m Pondering (Mar 1 – 31, 2019)

Inspired by Tim Ferriss’ Tribe of Mentors, you’ll find thought-provoking quotes in all my income reports.

These are the quotes that inspired me and changed my thinking in March. I hope you find them just as insightful as I did:

“Emptiness is the fasting of the mind.” — Zhuang Zhou (4th-century BC Chinese philosopher)

“Kindness is the language which the deaf can hear and the blind can see.” — Mark Twain (American writer and humorist)
