I recently decided to accept a counter-offer and subsequently declined an accepted offer. A day after I made this decision, I realized what I had done and that I had already mentally checked out of where I currently work, and I am feeling immense regret, especially as the other offer had a more promising future. From this experience alone, I don't think I'll ever take a counter offer again...Live and learn.
Now my question is, would it be possible in any way to salvage the offer I had reneged? I do have a unique skillset that is hard to find that they are interested in. I'm wondering if its worth a shot a week after this poor decision...or perhaps I should give it a shot in a couple months? Fully understanding that I might not get anything back.
