#I created the scientifically best sleeping schedule

I think this is a fantastic idea. There are multiple ways you could approach this idea. But here are my thoughts on for a good thumbnail and title. For the thumbnail you could eith have a side by side comparison with on person tired and the other happy and healthy OR you could have a person holding up a list with things to get healthier sleep. FOR the title the title you say above could work but you could make it more interesting like; adding a time, all caps the "scientifically" part or just make it more powerful or tap into a certain emotion [curiosity perhaps?]. These are just my ideas though so you can disagree with me all you want.

I would definitely click on the video if it showed up on my feed. My suggestion would be to pack a powerful story to why sleep is that important and how you are using science to make the most out of it. Honestly, I think the story would sell it to me on why to watch. I'm sure you already have an idea on how the video should go, but this is what I could think of as a suggestion.

You’re fine if you can actually deliver on this

The title could use some work, but I would like to know what you will be exactly doing in the video so i can better help you how to improve this
