Not much - if anything - I can add to or disagree with from Tony and Mr Cool, except that it's time for a (brutal) reality check Regret, and you won't like it.I suspect Mr Cool is on the right lines here - my sense though is that you are yet another individual who has simply decided they want to do something too later and with too little forethought. A PhD is a major undertaking and to admit this as being the 'fatal error' at best shows a lack of research on your part, that you undertook it when some basic due diligence on your part would have revealed that you would be graduating behind your peers, and therefore lose several years of working experience in the real world. Sometime we just have to accept that in the real world not everything is open to us: I would like to ride MotoGP professionally rather than be a HH, but at 36 I suspect its too late, and I don't have experience of riding competively (aside of dodging the odd police car and kid in a hatchback). So I can sit here and try to get myself in somewhere, leading nowhere, in MotoGP, or do what is open to me. And that's what you need to do. Accept that you have probably left it too late, the p/t MBA will at best be a sticking plaster on the problem (and an expensive one at that) and leave it there. Plenty of other careers out there.Here is the alternative: you take your p/t MBA at considerable cost financially, not to mention what the immense workload plus working f/t will do to your relationships and health (mental and physical). Graduated but on paper far off the pace and with no real commercial experience, you will either wind up picking up pieces of 'consulting' work here and there and drift into some shadowy interim career of being average but cheap, or you will work your way into some sort of semi-consulting role with a strong research basis on the promise/hope of getting client facing, it won't happen and you'll be here again, only now bitter and disillusioned with the choices you made.Think again Regret, turn back and do something more adjacent to where you are now.Or I could just have said I agree with Mr Cool... would have been a shorter post..
