Minecraft wiki entry for Beginner%27s_guide, associated text: By the end of the first day, your shelter is likely to be primitive and small. In the days afterward, you can build a better home, in any of various forms. Some natural extensions include a back door, windows, a surrounding fence, and even traps for monsters. Others are beautiful houses. If you build one and you don't like it, just build a different one. Remember that any time you pick up your bed, your spawn point reverts to the default (that is, random within 20 blocks of the world spawn point), until you not only place but sleep in (or at least "use") a bed again. For this reason, if your home is not very near the world spawn point, you should eventually use a compass to locate the exact point, and build a shelter there, or keep enough wool and planks to build new beds in new locations to keep your respawn point nearby as you explore the world.
