Fellow speaker,
Your hobbies provide analogies for your speech. For example, if you are a skydiver and you are doing a speech about buying stocks, you could use the analogy, "Buying stocks is like skydiving. You prepare and get everything ready beforehand and then, at some point, you have to jump out of that plane you're in and trust that your preparation is going to work for you."
Hobbying,
Tim
