[GianFabien]

I have switched careers multiple times. Electrical engineer to computer engineer to systems programmer to systems analyst to business analyst to IT support and then network engineer to academic and now back to programming mechatronic systems.

Although I've never given it much thought, my switching has always been into a field that I became interested in. Applying the principle of adjacent possible, i.e. using my existing skills to provide the foundation for stepping into a new field. In hindsight, the downside is that I probably would have had a more lucrative career by not jumping around. But I had fun and when the fun left, I would start looking for new opportunities.

It might not be obvious, but I tended to work for smallish companies who were ramping up in the area that I got hired to do. Obviously large companies are far more interested in candidates who can prove that they have 5+ years experience doing exactly what they are looking for.
