Awesome Seeds!
One way that I found that is pretty fun for finding cool new seeds is just to try random, easy to remember seeds, and see whether or not you like them.
Here are some seeds that I personally like and hopefully you will to!
1. 93819220
This should put you on a small island with some essential resources (e.g. wood, dirt, sand, gravel (the things you need to call it an island), and cows. those are definitely essential.
2. Middle Earth
This is not a particularly special seed, but it is a pretty nice plains biome with a nearby swamp, an oak/birch forest, a dark oak forest, and a small hill with one flat side good for digging either a mine or a house into.
3. 999999
(I need to check if this one works)
~POCKET EDITION ONLY~
Should spawn you near a nice, large, village, that has a nice lake nearby.
4. 999
(Sorry for the boring seeds!)
Another not-so special seed, but I use this for a lot of my worlds, as it spawns you in a plains biome next to an ocean with mountains surrounding it. There is also a swamp on the other side of the mountains.
~NOTICE~
I will try to edit this as often as possible and check the seeds are still working, but some of them might be out of date!
