Just wanted to share this cool thing I did in Minecraft. I was in this cave and I found a chest with a saddle in it. As you know, saddles can't be crafted and are somewhat hard to find so I was excited to find and ride a horse. By this point I was pretty decked out with Diamond tools and steel armor so I figured I'd leave my island and go find horses to domesticate and ride with the saddle. So one morning, I got in a boat and left my island in search of someplace that would have horses. It took me about 5 or 6 game days of walking and camping for the night until I finally found a grassland with a small herd of horses. I started a new homestead with a fenced pasture and small house in preparation for my horse ranch. Everything was set up so when it finally came time to start taming and riding my horses I checked my inventory and chests. I forgot to bring the saddle.
Now I suppose I could follow my compass all the way back to my original Island but I'm even not sure if it was pointing to the island, or to the place I spawned which was out of sight of the island. In my experience navigating without an exact idea of where you are is difficult and I've gotten lost even with a compass. Besides I'd never find my new homestead again since it took so long to get there. So it was not meant to be.
