Welcome! Fuel yourself and rest yourself, you seem to have the swing of things well under control, though. Routes will change as well as your cycling skill and comfort on the streets increases.

May want to keep the bike as-is and maybe look into a different bike (off eBay/Craigslist) after you've had a few months to assess what it is you really want/need (ie, maybe a roadbike with rack lugs for example)

Congrats, and keep it up
