Do you play an instrument? Guitar? Piano? Flute? Every year before Christmas do wish that you had started to learn some Christmas music? Why not pick a few carols to learn properly this year, the way that you have always wanted.
Most Christmas standards are actually very easy to play and the you will find versions of them that are to your skill level. Even if you play the easiest version that you can find there is a great sense of accomplishment to it.
If you don't play an instrument why not dust of a book of carols and learn the words to them properly. Everyone can start the first line of a Christmas Carol and then it tends to fizzle out very quickly.
