How do I get back to my first spawning point?
Solution 1:
This is anecdotal so someone will need to confirm this, but destroying or blocking the last bed you slept in will cause you to re-spawn at your original spawn point after you die.
Solution 2:
You no longer need to kill yourself to get to your original spawn. Most recent Minecraft versions (don't have access to the wiki to check) have compasses that now point directly towards your original spawn.
This may make finding your bed harder, but will make finding default spawn as easy as crafting a compass and following the needle.
Do compasses still point towards your spawn/bed?
