My passion for tech outside of work extended into my 30s but by late 30s, after having children, it dwindled. It has recently picked back up again in my early 40s as I can view the world somewhat through my children's eyes and their curiosity and creativity is infectious. So my advice is to try to be curious about the world again and if that curiosity flows to building technical things let it take you there, if not it might take you somewhere else just as interesting.
