My advice to you would ve to have fun! Make your town how you wanna make it!
Talk to the able sister's everyday, especially the one sewing in the back, you can eventually unlock qr codes from her. Get a shovel and dig up any marks in your town for fossils, donate the ones you don't have in your museum, catching bugs makes a decent chunk of bells and sp do turnips but sell your turnips before Saturday or they will go bad!
