I need a speech writer

I am the guest speaker for a Martin Luther King Day program on Jan. 17, 2022. The theme is "Breaking Barriers Through His Dream." I've started writing but now have writer's block. My point is to show it is the best of times (because as black people we are making strides and breaking barriers) but it also the worst of times because we are making progress and challenging the status quo. Our progress is awakening racial hatred and stirring the pot of political polarization. I want to leave them with a call to action on how to unite, which is our biggest challenge as a people, and to continue to break barriers.
