The biggest obstacle has been the internet. The internet forces us to keep current, as web sites change, browsers change, and security becomes more of a problem.
Aint that the truth!
On the other hand I
love exploring the
bleeding edges of evolving technology. To coin a phrase from Agtha Christie's fictional Belgian detective, Hercule Poirot, it challenges me to "exercise my little grey cells" and keeps me from getting or at least feeling old. So I would always be trying the next "new" thing even without the spur of the internet. (FWIW I love my 2 day old iPhone X)
