In my early 40s and working in tech. I do really like my profession and plan to keep working (silly me?..). Since the start of my career, I normally switch jobs every 2.5 - 4 years. Sometimes due to redundancy, lately due to higher pay and better title. I also get bored when stayed in one place for too long, this is just a personal preference I suppose. However, I am wondering if my switching model is sustainable as I am getting older. I want to prepare for it i.e acquire extra skills now, before it is too late.
Any advice/share of experience is welcome. Thank you so much.
