I read an interesting articled titled "The Quit-Lag Phenomenon". What it basically says is that once an employee is set to leave a company, that employee can become very productive by doing things that seemed impossible or not so important before. This is due to removal of stress, concern of company politics, long term tasks etc. I don't want to write too many details of the paper, as you can read it yourself. What I do want is to give the punch-line, as I understood it:
By removing stress factors from your working environment and by taking care of details, you'll be able to be more productive and be able to address tasks that otherwise would seem intimidating. I think this is something worth trying.
