What I’m reading —

What I’ve Learned in 10 Years of Zen Habits by Leo Babauta

Leo shares his lessons learned from 10 years of writing on Zen Habits. His insights from his personal and work life are really valuable. Personally, I resonated with his focus on “intentions” over “goals”. When your intent is right, you’ll find a way to create value and make it more fun to go through the process. His lessons are also a great reminder that it takes time to build something great and at the same time life is short so enjoy the moments that accompany the journey.

Books, documentaries, or podcast episodes I’m enjoying —

The Tim Ferriss Show – The Return of the Money Shot

This episode features an “ask me everything” with comic, Whitney Cummings. She opens up to her experience of being in codependent relationships and how she’s been able to overcome those experiences. It’s a really open and honest podcast episode that anyone can benefit from listening to. I also appreciated her take on the benefits of having a dog (as I’m thinking about getting one some point in the next 12-16 months!)

A quote that’s inspiring me —

Productivity tip of the week —

Vitamin D supplementation

Disclaimer: Please consult your physician before you decide to add a supplement to your diet.

It’s mid-winter here in Toronto and this is the time of year that Seasonal Affective Disorder begins to set in. Personally, I’ve felt a little down over the past couple of weeks as we’ve only had sunlight for about 2-3 hours per day.

One of the ways that I ensure I stay healthy and keep my mood up during these months is through Vitamin D supplementation. There are very reliable studies that have looked at the wide range of benefits of Vitamin D including immune health, bone health, and well-being. has a really good overview of Vitamin D.

The current recommended daily allowance for Vitamin D in the US and Canada is at 400-800IU/day but that is often regarded as being too low. The safer upper limit in the US and Canada is 4000IU/day and some research even suggests up to 10,000IU/day. Personally, I take closer to 5000IU/day and feel no adverse effects.

If you’ve yet to add Vitamin D to your supplementation, I highly recommend it especially if you live in the US or Canada. And if you’re curious as to what product I use, I have a recommendation below.

Product or service I’m loving —

Thorne Vitamin D/K2

I like this product for Vitamin D supplementation because they use D3 instead of D2. D3 is used more effectiely by your body that D2. The liquid drops also come in a medium-chain triglyceride oil which makes it easier for your body to absorb. I also take my Vitamin D with krill oil which further helps with absorption into the body. It’s not a cheap product but well worth adding to your morning supplement list.

Again, consult your physician first to see if this is right for you.
