How to make my Ted talk better

I started to write my Ted talk like weeks ago. I had some ideas about my topic for what to write and how to support it. I gave a lot of examples to support my idea which is to hard work beats every situation even the worst ones. I used real story examples of players who had a bad life experience at their past life. So I have a good topic which I can support it with a lot of examples. However I need to add something and show a picture of those players so the audience would recognize them. I should show a video of their experiencences which would help them to realize them by seeing it other than hearing it. I should be more specific on the things when I try to explain the topic. Also I wanted to inspire them to work hard and try to make them a good athletes. So people have to inspired by my talk. That is my goal so people would want to work hard for their sports. There are a lot of things that I have to work on my Ted talk because giving example is not enough for a person to inspire. So I need to find different ways to make my talk inspired. I am thinking about giving one of my life experience to make them empathy over something that would happen to random person. So that's how I would improve my talk.
