In reply to Christi323:
Learn to re-thread the rope safely and confidently, both threading a bight (quick and easy through big rings) and re-threading a single strand (while staying on belay) which is sometimes necessary where the anchors are small or clogged with knackered old krabs. Learn to do it without a locking krab for the time you forget it or drop it.
If you're pumped and full of adrenaline, take a moment before you start. If midges are killing you, suffer, don't rush.
Never lower off textiles, your rope will cut like a saw.
Learn to abseil, it's useful in extremis but can usually be avoided by abandoning a krab or two. Be willing to abandon gear, better to lose a £7 krab than nick the sheath (or worse) on a £100 rope.
Pause and think through the 'what ifs' every time. Don't just learn a technique and stick to it. Think. How does that work? What if that bit fails? Is the rock sound (it changes, don't assume)? Did I tie that right and catch both loops? Before I unclip this, what will be left attached to me and the wall? What if I drop this now? Am I actually still properly on belay before I lean back? If you don't like the the answer think again and do something about it.
It's not difficult but that's part of the danger!
