how do i form/come up with a compelling/high concept/exciting

When you have an honest story idea you know is good without trying to be high concept or exciting.
Just fucking write what you know or want to know, and it'll either be good or bad. Then, if writing really is your passion, you'll try again and again until you get it right or strike gold.

Find a newspaper article you find exciting and fictionalize it. Plot is just a device for exploring characters and themes, no one cares if yours is très original.

Watch this course, OP. He covers plot in later lectures but do not miss the early ones:
