This is the approach I take too. I encourage company training but, they will train in what is right for them more than what is right for the employee anyway. The training I do with clients is an exceptional case because it is for the individual as well as the company.

As I have found a new passion in blockchain, I have done the same to learn and be able to have conversations related to it as the future may hold opportunities for those who do.

The value of being into the experience early is yet to be known but I would say future knowledge potential is highly leveragable.
