Ive started playing minecraft agan, Im already bored!

Try to join some RPG servers , do some new 1.14 raiding defense , maybe install some mods that add dungeons etc... but vanilla gameplay isn't really interesting especially if you have played minecraft before.
challenge yourself to build crazy stuff in survival maybe

The best thing to do is just to play survival or something with friends as it normally kills the boredom.

I would recommend finding some servers or mods that you are interested in. Of course, this depends on how well your computer can run mods, but I would recommend a themed pack - there's this one called Decimation which is a zombie survival multiplayer pack (it has its own server).

If you play with your friends you will see that isn't bored

same I started playing it yesterday and I kinda got bored of it after a while it's not the same as it used to be

Me too get bored when playing the same game again and again.
It's time to switch to a completely different and new game.

I feel the same way, but some modpacks help me stay interested for longer.

I get you man hahaha Minecraft used to be fun when we were kids but not anymore :(

mods are fun for the game, tekkit i really really enjoyed now
