On a serious note. Pick the thing up and play it DAILY even for a short time. You improve rapidly if you do.
I agree with Declan that smaller boxes are quieter and therefore marginally more popular with other musicians. You are going to have to live with the prejudice of others against accordions because of the inconsiderate players who do drown out a roomful of instruments because they don't realise/care/think that they could be quieter.
