You need to see comedy as your profession if you want to take your hobby from cracking jokes to being a successful comedian. You need to develop a habit of sitting every day for a few hours to write and improvise your jokes. The good comedy will always take practice. Pick up lines from your conversations that you feel can build a story. Put the daily events of your life into perspective and find humor in the details. Learn from other comedians about hitting a punchline and delivering a good story. Write a small set and slowly grow with it as you practice it every day. Find out how you will close in your set before you start coming to the end of your time on stage. Develop a persona that people would want to see more before you try to impress them with your jokes.
