What should I include or avoid in my purpose of stay document for a DTV visa application in Thailand?

I'm applying DTV thru the discover thai nature course, the embassy has only mostly asked for a purpose of stay document detailing my plans in thailand (like what I intend to do on a daily basis, income/expense ratio, and if im staying for less then 6 months this time when do I plan to return). I'm currently on a gap year (finished study already) and will be living off savings until I get a new job. I dont want to over complicate the visa process obviously, what would you recommend me to (not) include in this document?
