How can I fix this run on sentence? Is it run-on sentence? [closed]

It sounds like this would break apart at its natural joints. Keeping it as one long over-explained thought, bringing in the source of each thought, and what they mean to you with regard to going to school there, and how exciting it would be... Well you get the idea. Separate the ideas and make each one worthy of inclusion. If you can't then leave it out. There are plenty more.
