That's ok - I did the same - I tried to make myself really look forward to each contraction. It was hard at times but it did help. After a bad one - I thought, I hope the next one comes quickly, then I can meet my baby.
Another thing, if you are having a bad one and puffing and panting - I for some daft reason started doing the 7 times table! It was really difficult (maths never was my strong point anyway) but it really took my mind off things - got funny looks from the midwife when the contraction was over and I asked her was 7 8's were!!!
