1) Getting a scanner (should get my 30d on Tuesday or Wednesday), plus getting 'L' glass
2) Seeing the birds in the garden, loads of them, all wanting there piccy taken
3) Having a Great spotted woodpecker to close too focus - less than 1.5m away - and not be afraid of shutter noise when he did move further away!
4) Keep your eyes peeled, move slowly and deliberatly
