Viral Marketing Viral marketing is the process of getting your existing users to refer others to your product. It can come from different forms: Pure word of mouth: people naturally tell people about your product. Inherent virality: people can only get value by inviting others (chat app, social media app).

For nearly three years, James Clear has pushed out a new article on his blog every Monday and Thursday. No matter how long, short, compelling an article was, it got published on the site on time. He said that he wanted to write consistently to find his voice, build an audience, churn through average ideas to discover great ones. He didn’t know whether an article was popular or not, but he believed that if he did not miss a day, he would eventually become a better writer and hopefully make it big someday....

I’ve tried multiple goal setting methods and habit apps in the past but normally I would find them pretty complicated after 1-2 uses. However, since I heard about James Clear’s Goal Setting Method, I’ve been using it actively since. Personally, I think it’s a super clean, simple, yet effective way to set better goals using 4 main strategies:...

A year ago, in August 2019, I shared this Ultimate Go Study Guide project on GitHub, and surprisingly, it got a lot of attention from the community. Fast forward to August 2020, it now has over 11K stars, 900 forks with the help of more than 20 contributors. The project is a collection of my notes while learning Go programming language from Ardan Labs’s Ultimate Go course. Honestly, I couldn’t thank Bill Kennedy and the Ardan Labs team enough for open-sourcing this wonderful material....

You shouldn’t ask your mom or anyone whether your business is a good idea because it’s a bad question and invites everyone to lie to you at least a little. The Mom Test is a set of 3 simple rules for crating good questions that even your mom can’t lie about: Talk about their lives instead of your idea....

Focus on high-leverage activities. Leverage: impact produced / time invested. 80/20 rule: 80% impact comes from 20% work. Focus on not more hours but more value per limited time on the task. Increase leverage by: Reduce the time it takes to complete the activity (default to half-hour meeting instead of one-hour one, automate manual dev process). Increase the value produced (have a clear agenda beforehand, prioritize tasks based on launch date)....

Software solves business problems. It doesn’t matter if your app has the most elegant architecture, it must create value for the company aka brings in revenue.

Actual goals: add revenue, reduce costs - “wrote the backend billing code that 97% of Google’s revenue passes through”. That’s why Quants makes more in bonuses in a good year than many talented engineers will earn in a lifetime....

Concentrate: Do one thing at a time. Exceptional work is always associated with periods of deep concentration. Have a clear purpose on what you want to learn about. What does it matter? How is it applicable to my life? How can I apply it? How can it help me achieve my goals? Create and connect: People that learn quickly or have a so-called photographic memory apply their creativity to everything they learn, using the SEE principles....
