Awaiting delivery of my new bike (most expensive purchase to date on a bike) and I want to keep it safe and running well for as long as possible!

Wondering what kind of daily, weekly and monthly checks I should be doing to it?

I hear of things like needing to re grease the chain etc and all of the specialist bottles of cleaning agents needed etc and I know this can get very extensive and complex, but as mechanics what do you recommend I do as a beginner to keep my bike good?

Thanks
