I wouldn't mind removing all the mistakes I have made. That would be exhausting and take forever. Honestly, it's one of the spells of my life that has been the most perfect. Not because I did the job perfectly, because of course I did it very imperfectly, but because I enjoyed it so much. What would I change? I complain a lot. I whinge, I more or less communicate in levels of complaint so I wish sometimes I didn't just spend all my time saying, 'I'm working so hard, what do I get in return for this?'.

That place you've always been heading for, but never expected to go.
