Try thinking about how you want your town to look before placing PWPs. A lot of people regret placing undemolishable PWPs (Cafe, campsite, etc) in places they hate. Get a good idea before putting them.
Collect bells. You can catch rare palm-tree bugs at the island past 7pm, or you can buy bells from users here. Probably better to try to earn them yourself for a more interesting experience, but if you urgently need them then there's always people to help!
Collect lots of furniture and clothes, and sell them here for IGB (in-game bells) or TBT (bells on this forum; shown below your avatar/profile pic). Both are useful to get rare items here, however TBT is usually more preferred.
Try thinking of what villagers you want in your town. As well as setting a theme (or no theme, that's fine too), some goals, good friendships with your villagers and plans to improve your town little by little.
You can try looking at dream towns for ideas, however they will probably make you jealous or upset at your own town. If you're sure you're fine looking at other towns for more ideas, then do so.
But best of all, have fun! Don't rush anything, play freely and to your liking
