If you have a long story that can make your audience bored to death, here's some tips to make it interesting:
Cut your long story into several parts, and use sub-headline at the beginning of each part.
Take your time when writing the sub-headlines as they need to keep your readers` attention captivated.
Keep each and every paragraph short.
You can also use bullet points to list several things that may sound familiar with your audience.
Read your story several times, and tweak and rewrite your story if you have to. Remove some unnecessary part.
Put a short introduction about yourself and who you are, but don't get too long. Just make sure you explain why they should listed to you, and continue with an interesting (or sad) story. A story about how you also experienced that problem(s) in the past.
