So I juuuust turned 30. Is this the fabled "mid-life"?

So I turned 30 in November. (Yeah that's right. Scorpio baby!!)
And now I feel like my career isn't what I'm supposed to be doing. Being an electrician just isn't cutting it. I've taken laboring jobs the last year. Threw tires in a shop, worked in a warehouse for Amazon for awhile. Hell I even got on a suit and did door to door sales, which is what I'm doing currently. Shouldn't I have a career figured out by now? I just feel like I've beeen living someone else's life for so long. Is this just a phase?
