That's about all you can do really. The thing I found is make yourself invaluable. That means throwing what interests you technology wise under a bus and learn stuff that isn't glamorous. Pick a niche with a perpetual vacuum yet hedge on something ubiquitous. For me I do AWS crap for the ubiquitous and Linux sysadmin for the vacuum. There are very few people around who truly can do the latter. I picked 20/30 different career paths and scanned around job sites for stupid salaries and contract rates where I don't have to invest much and just do that. But always have 12 months cash in the bank. That doesn't have to be 12 months of luxury, but 12 months of survival. Shortened: minimise risks through security and skill hedging.
