Yeah, the only thing I'm afraid about is leaving this job for another job of the same quality.

I did an interview at a company where my old mentor works and they've been looking to expand and hire new engineers, but it's been 2 months. I just sent his boss an email to see if anything's changed, because that'd be my #1 choice -- work with a mentor I know is good and if he says the place is good, I trust his judgement.

Now to wait and see if luck is on my side -- but I've started applying elsewhere, so I'll keep my fingers crossed.

It's just scary leaving a job when I don't have another lined up.
