I feel that I should record for posterity that my favourite poem is Rudyard Kipling's "If". The subject of favourite poems came up recently in a conversation, and for some reason I couldn't think of one on the spur of the moment. So in accordance with the well-known mnemonic principle of 'write it down and even if you never look at the writing again, you'll remember it', let me just say that I absolutely worship and adore that poem, and it's always going to be the one that springs to my mind when asked for a favourite.
Then I'll follow it with an apology for choosing the poem that everyone lists as their all-time favourite, but it really is. Sorry.
