Chopin minute waltz

[bleaks33]

Hi all,
Self taught pianist here, am thinking about trying to tackle Chopin's minute waltz. I've been learning for about 2 years and currently have nocturnes no 2, 20 and preludes 2, 4 and 20 under my belt. I recognise that none of these pieces are similar to the minute waltz regarding the technical demands, does anyone have any suggestions for pieces to learn beforehand? Am I too ambitious?

Thanks.

Db major scales, and more Db major scales
