I wouldn't worry about that one bit

Oh - I don't worry about it! I used to, but I don't anymore.
Live would be pretty dull if we had learnt everything that there is to learn.

It's a bit like looking backwards. I used to look at things I had created some time ago and despair at how bad they were. Be it code, writing, woodwork or anything else. I now celebrate how bad they were because it shows how far I have come since then.

Like so many things in life, it is all about you choose to frame them...
