What about Luau, Fair, and early birthday gifts? Do you have plenty of gold star without fertilizer? Do you ignore socializing until you have Rabbit's, Diamonds, and Prismatic Shards galore?
Other than when I first got the game in March and wanted to befriend everyone at once, I don't prioritize gifting and birthdays anymore. I'm usually fishing or mining all day the first year and don't want to break away for an hour or two from either of those activities to find someone in order to gift them.
The first year I'll have a gold cauliflower that I take to the luau and that gets the highest grade on the community soup. And I will attend the festivals and talk to everyone for friendship points, except the spring dance.
If someone is near me while I'm moving around, I'll right click chat with them. If it's the worst luck day and coincides with someone's birthday, I'll gift them. Although I never gift anything expensive like diamonds or prismatic shards. Most people have a loved gift that isn't expensive. And if not, their liked gifts are generally plentiful somewhere in my inventory.
I don't think I need to go beyond that, especially when you finish the bulletin board @CC, your heart value goes up a decent amount with the whole town.
Now I will say, I do try to do as many quests as possible especially the mining copper/kill this mine monster/fetch this gem quest. You have 2 days to do each one and they help friendship points and more importantly give you early gold when you're still struggling a bit.
Also, starting in year two, I still don't prioritize gifting but do emphasize it more. In my current game (late spring year two), I'm pretty sure half the town is over 6 hearts and the rest above 4 hearts even with my lazy attitude towards befriending them, except maybe Kent who just showed up. I don't see Sandy much but take a gift everytime I need to buy something at her shop. Krobus and the dwarf are kept happy with horse radish and dwarf scrolls respectively - both of which I have in abundance. I now always keep a stack of fruit on me that I pass out when I come across someone, I keep tea for the mayor and caroline when I go to pierre's. Amethyst for the girl who eats them. And so on.
If I keep this up, I think everyone will be at 10 hearts by end of year two. And I think that's fine, no reason to rush it in year one at the expense of doing something else in the game.
