I love a good notebook and pen for fleshing out ideas. I have a Zebra pen everywhere I go. I prefer the .7 mm fine point.
Products and Services I Use
I saw Russell Brunson using a yellow notebook in a video to come up with ideas and knew I had to implement that in my life. When you spend a lot of time on a computer, physical pen and paper hits differently. Definitely has to be yellow paper as well. I typically have 2 of these in my bag all the time.
