In my twenties, I ate what I craved, slept inconsistently and rarely did any exercise.

It was fine until it wasn’t. 2017, the year that changed my perspective on the power of foods, exercise, and sleep on our health.

After a few months of celebrating my 30th birthday, I was due for an annual physical. To my surprise, my vitals moved from being perfect to borderline and on track to be requiring some medications in the next 5–10 years.

The less you have, the more you can focus


Over the last 13 years, I have moved 10 times. From multiple trips, cars, boxes, and rental trucks, there were costs to picking up and going somewhere else. Thousands of dollars were spent.

Every time, I upsized, I accumulated more stuff. Every time, I downsized, I donated and sold stuff. I spent more when upsizing my living space. I lost more when downsizing as most of the stuff we buy, depreciates in value.

It took me a long time but it became clear: having more meant spending more. …

How I evaluate my startup ideas

To have a successful startup, you need a great idea in a growing market, a great team, a great product, and great execution. Thus, before you write a single line of code, you need to evaluate if your idea is worth spending years building it.

I have founded two companies (one exited, second in progress), led product & engineering at two startups acquired both acquired by public companies. Over the last 10 years, through several mistakes, I developed some questions on how to evaluate startup ideas.

The following are the four questions that I ask myself when I’m evaluating a…

Whether you’re an aspiring entrepreneur or going through a pivot, finalizing a startup idea could be overwhelming.

A good founder usually has a bag of ideas. Having multiple ideas is good, but not ideas are created equal.

In this post, I’m sharing the process that I use to decide what ideas are worth executing and how to eliminate weak ideas.

Because thinking is hard.

Cognitive biases have become quite popular in mainstream culture in the last decade, thanks to books like Thinking Fast and Slow and Predictably Irrational.

There are more than 100 biases (188 according to an exhaustive infographic⁴). I’m going to focus on five common biases, share what they are, and how to avoid them.

1. Confirmation bias

Confirmation bias occurs when people actively seek out information that confirms their opinion and disregard information which contradicts it.


  • Getting news from a single source.
  • People who support or oppose a particular issue will not only seek information to support it, they will also interpret news…

A new standard for team communication and knowledge sharing

When Herman and I decided to start our company, we knew we wanted to operate as a fully distributed company. We were drawn to the benefits of having the freedom to work from anywhere, access to global talent, and the potential cost savings.

We had also worked in distributed teams before, and found that it made us more productive. There’s a strong culture of written communication, which builds transparency and allows us to be less distracted in our work.
