Im not surprised! BoTW is a boring game. It has a short main story and some memories to collect (which are basically the most boring cutscenes in all of gaming). Besides that what is there to do? Run around the world and Collect 900 pointless seeds....? Not for me thank you.
Just move on to another game or take up knitting.
I don't know
It's okay to not like the game, but to say the game is just about collecting Korok Seeds(of which the game was designed to not collect them all, only about 200 is really necessary), is a fallacy.
Finding 120(Now 136) Shrines that each have their own puzzles and challenges, and provide the main upgrades of the game.
Finding 4 Fairy Fountains hidden throughout the game, which will upgrade your gear
Building an entire town from scratch
Going through 4(now 5) Divine Beasts.
Playing minigames such as Boom Bowling, Horseback Riding, Archery, Flight Mini Games.
Finding horse stables.
Collecting materials which are scattered throughout the world.
Searching chests in the overworld for nice weapons.
Finding a Horse God.
Fighting enemies, which then nets you more materials for money, upgrades to armor, or for potions.
Finding all 12 memories which provide story cutscenes.
Finding unique shops, such as a shop that lets you dye your armor, or a monster shop.
Mining Ore for money and upgrades
Finding Kass within the overworld for a unique Shrine Quest
Locating the 3 dragons, and doing the tasks associated with them.
Finding the Master Sword within the lost woods.
Starting sidequests that build new shops, for new and unique equipment.
Finding unique armor pieces, such as the Zora Armor set, or the Barbarian Set(which are some of the most useful armor in the game).
Finding and taming new and unique horses(such as Zelda's Horse, the Giant Horse, or Ganon's horse)
It's okay if these things aren't for you, but being reductive and stating hyperboles is not going to suite you any favors. There is plenty to do within the game, yet you choose the content that os the least consequential, and something that is not even the main content of the game. It's like saying that in Ocarina of Time, "All you do is collect 100 skulltulas". It's just as erroneous of a statement and provides the exact same implication.
As for you OP.
BotW is designed so you can finish the game once you think you have had your fair share of content. It's okay that the game isn't for you, no game ever will be. So just finish the game, beat Ganon, and be done with it(if you hadn't already). There is no need to "force" yourself to like it, it's perfectly okay to not like it. So just try playing a game you enjoy!
