The first thing that you should do on your journey to becoming a stand-comedian is to buy a small notebook. Keep this with you at all times and begin writing immediately. It’s important to get in the habit of recording your observations. Don’t worry about writing jokes for now just start paying attention to your surroundings. Do you see anything that doesn’t add up? Something peculiar or strange? Something ironic? An odd pairing? A truth about the world? These are the types of things that you want to start being aware of and writing down. They are telling you something about how you perceive the world and will be helpful when you go back and start writing actual material.
In my opinion you should have three types of notebooks although for now the pocket sized one is just fine. I have my small notebooks I keep on me always that I write down my observations. I have my larger notebooks where I expand on the ideas I have in my smaller notebooks. This notebook is more of a joke notebook but is not just that. It’s really where I expand my ideas an explore them. Sometimes this result in jokes. I think it’s good to write your solid ideas in multiple places. Repetition is the key to memorization and also it’s good to have copies in case you loose your notebooks. Some people like to write on there phones and computers but I recommend writing it out on actual paper with a real pen. I use the digital space to keep files with all my jokes and ideas but in general I think it’s best to put pen to paper.
The third type of notebook I recommend starting is a more traditional journal type. This will probably contain the least of your actual material but I can be useful to see where you were at during different times in your life. This journal type entry can be therapeutic but also help get the creative juices flowing. The most important thing is that you write a lot. Write daily. Write in different styles. Go back and read what you’ve written. Edit it. Maybe the three notebook system isn’t for you but that’s wha works best for me. Bottom line – start recording your observations right now and when in doubt always just write it out.
