Ask HN: How to continue improving as a self-taught data scientist?

Hey HN!

I am a medschool student but I have been doing data analyses for other students in my spare time with R. In fact, I even hosted a one day workshop on stats and I am planning on doing a second one!

So far I haven't participated in Kaggle competitions and I am currently learning multilevel modelling and Bayesian analysis. I would like to continue improving my skills and attract more work, what do you think I should read or do? I would love to work with medicine as well as statistics in the future but I believe I still have a long way to go :)

Thanks!
