I am writing to express my gratitude for the opportunity you have offered me to speak at the upcoming event in Salt Lake City, Utah.

However, after careful consideration, I regretfully decline the offer to speak at this event. Please understand that my decision was not made lightly. I have taken into account various factors that have made it necessary for me to reconsider my participation in this event.

Therefore, should the opportunity arise in the future, I would be thrilled to consider participating and contributing to similar events organized by your organization. I would also like to extend an invitation to keep in touch for future speaking engagements or collaborations. While my current circumstances prevent my attendance, I genuinely wish for success and fruitful discussions at the upcoming event in Salt Lake City. If there is any way I can support your organization or provide assistance moving forward, please feel free to reach out to me. I truly appreciate your understanding and consideration of my circumstances. Again, please accept my sincerest apologies for any inconvenience caused. I am confident that the event will be a resounding success, and I wish you all the best in its organization and execution. Thank you once again for the opportunity to be a part of such a prestigious event. I look forward to future collaborations and the possibility of working together in the near future.
