I should admit something: I have almost no such hacks and I do not focus heavily on my processes and how to streamline them.
Now, I do think I’m a fairly productive person. I get a lot done during the day. Since I started my own business, I tend to balance the day with research, writing (which is what pays bills, if you will), customer support, site maintenance, and development.
I love this post by Brian. We can get caught up in all of these things that you “should be doing to be productive” instead of doing what works for you.
