7. Don't dig a hole you can't get out of, literally

Minecraft Pocket Edition: Top 10 tips, hints, and cheats!

Sometimes in Minecraft you can't resist the urge to dig. Just make sure when you do, you aren't digging a hole you can't get out of. I've been guilty of this and it's not easy, especially if you don't have any torches on hand and have no sticks to make any. It's another reason I suggest always having at least a few sticks on you, if not full torches. It's a pain to have to fashion makeshift steps in the dark, and the torches will make it easier if you do happen to get into a tight spot.
