So I have resigned from my current job in Feb but as it is a 3 month notice period I am still working there. I have a terrible habit of thinking the grass is greener elsewhere and hence move jobs a lot but now I feel like I have made a mistake as the pro's of the job have been more evident during my notice period and I now regret resigning, even though it will be a promotion in the new job. I have started the handover so can't change my mind but I now am regretting my decision!
