broken finger, what to do the next 3 weeks?

A silly accident at home and I have a broken middle finger in my right hand. A real bummer for piano practice. I would like to do something the next 3 weeks and I was wondering if you had any advice on what to do with the left hand only and if there was any material, course, pdf at OS or anywhere else on this matter.

Thanks in advance for your help and keep up the excellent courses at OS!!!

Cheers,
