My daily habits are one of the best parts of my life. Without them, I feel like I'm running in sand in life. With them, I feel like I have solid foundation to build on. With a few challenging ones, I feel like I'm building on bedrock.<p>I've coined the term <i>sidcha</i> for Self-Imposed Daily Challenging Healthy Activity and written about the concept: <a href="http://joshuaspodek.com/js_blogseries/self-imposed-daily-challenging-healthy-activity-sidcha-series" rel="nofollow">http://joshuaspodek.com/js_blogseries/self-imposed-daily-cha...</a><p>My main challenging habits are<p>- Burpees, daily<p>- Blog posts, daily<p>- Cold showers, every fourth day<p>I did my first set of daily burpees December 22, 2011 and haven’t missed one since, so I’m about to enter my 6th year of that habit, nearing 80,000 cumulative burpees. I've written about it: <a href="http://joshuaspodek.com/js_blogseries/burpees" rel="nofollow">http://joshuaspodek.com/js_blogseries/burpees</a><p>I started posting daily on my blog, <a href="http://joshuaspodek.com" rel="nofollow">http://joshuaspodek.com</a>, in January 2011 and haven’t missed a day since, so I’m about to enter my 7th year of that habit, nearing 2,500 cumulative posts. Here's an archive of all the posts: <a href="http://joshuaspodek.com/archives" rel="nofollow">http://joshuaspodek.com/archives</a><p>I took my first cold shower in December 2013. I did them daily for a month and every fourth day since, so I just started my 4th year of doing them regularly, nearing 300 of them cumulatively.

The last time I went to sleep without brushing my teeth would have been in college, which would be around 1990.<p>Come to think of it, if you count not eating meat as a habit, I’ve eaten no meat since 1990.
