I think the most challenging aspect of Open Science is education. It is an enormously complex paradigm, with its own lexicon, practices, principles, and represents a quite high learning barrier in many cases. However, watching others develop their knowledge and skills is incredibly rewarding, and I find myself learning more with every new experience too. Ultimately, we all have the same thing in mind - a fairer, more equitable, transparent and rigorous system of scientific research, and watching the huge steps the global research community, and especially younger generations, are taking towards this is very inspiring.
