Let's say you only have 30 minutes. This could be in the morning, lunch, before bed. It doesn't matter. What are some things you can do to be productive. Reading emails or forums is one thing that I often do, but it's not very productive. Yet, doing something like making a splash page or writing good sales letter takes longer (at least for me).
I hope to get a list of ideas and write a article on this. Thanks for your contributions.
