There are always ups and downs but you sound like you're in a position where you don't have the experience yet to see that. Personally I'd make sure to have savings to bridge the gab should you be laid off or have trouble finding a job in the first place.

You've chosen a field that's probably on the much safer side of things in terms of job security so try not let it affect you too much. It's easy to say I get it but it'll be fine. Probably.
