It’s unfortunate that so many comments below are so stuck on how egoistic Elon is. As if they themselves are ego-less. I work in a 4000 people company with great culture. But even then egos are only skin deep and easily surfaced. Humans are not machines. Egos and emotions are the norm. Just look at yourself.

1. I think giving up at this stage is the the easiest thing to do - and I think it common due to the uncertainty about the future

2. Check that you can imagine yourself spending next few years doing what you are doing, just even more harder

3. If so, double down, as suggested above ask why, why and why. If needed, pivot.
