After 700 hrs in ksp there’s nothing new to learn.

After 700 hours of playing ksp I feel bored.

Teach me something I might never know about ksp.

If you play the main soundtrack backwards you hear "Jeb is dead".

Have you tried making an orbital ring around Kerbin?

 

Or, land a bunch of lit up landers on the far/dark side of Mun so you can see a face and/or words from orbit.

The "next level" of KSP is writing mods.
You might be surprised how many gaps you still have in your knowledge when you try translating it to C#.

[bewing]

Have you tried building good airplanes yet? Good spaceplanes? Hydrofoils?

Or perhaps the next level of KSP is playing mods. Things like FAR or RSS. When you scale the system up to real-world sizes (or add ullage and boil off, etc.) the game gets a lot harder again. Do you want to know what rocket science is like in the real world?

Personally, I find that redesigning my old ships to work better is my favorite thing to do.

Try building a large platform in orbit, and make small rockets. Now send those rockets down from the platform in orbit to the KSC. Orbital bombardment is amazing

Please list in detail every unique mission you've done, so we know what to suggest.

That should keep you busy for another couple hundred hours.

Try encasing the whole entire planet or a moon or even an asteroid in a shell. I just hope your computer is powerful enough

He's what you do. Take standard optimal design convention, and you put it in this pretty little box. Then you wrap the box up all nice and purdy like with this here ribbon. Now you take that nice and pretty box and throw it out the window... in to the path of a tractor trailer... with snow chains on.

Focus on style. form not function. Who cares if the end ISP is negative. If you have more parts that are non-functional then you baseline <insert automotive brand you don't like>. But if it has style and looks cool, and can do it's rate mission that's what matters here. After all the way I see it, if you're going to build a [rocket], why not do it with some style?

You could also try landing on Jool. You'll get there eventually! (100% working totally legit advice)
