Is the glass half-full or half-empty?

Visualise this: You were made redundant a few months ago. You had been looking for jobs, but the outcome was less than encouraging. The responses to your job applications, so far, were rejections. The rationale commonly given by companies was 'We like you, but you are too qualified for the position'. The reality was that the companies had found someone cheaper i.e. someone who was willing to accept a much lesser salary. The person might have less qualifications or experiences than you, but he or she was more economical.

Things appeared to be turning around. You went for an interview today and you had been offered a job on the spot. But, the salary was much lesser than what you used to earn in the previous job. Let say, £12,000 less. However, the company, which had just offered you a job, was willing to increase the advertised salary by £4,000. Hence, if you chose to accept the job offer, your annual salary would be £32,000. However, as much as you would like to accept the job, you were unimpressed with this salary and, more importantly, the daily driving to the head office (around 1 hour drive from your home to Heathrow). To check if you could survive on this salary, you estimated the figures of your monthly expenses and then deducted the figures with your monthly income. The result was 'grim'. After covering main expenses (e.g. rent, petrol, car premium, mobile phone bill etc), you would probably only have £500 each month for grocery or food. Since you would be travelling to and from Heathrow each day, it would escalate the mileage on your car and, thus, would cost you some maintenance fee (eg brake maintenance etc) on the car. Based on these figures, would you rather reject the job offer and hope that a better offer will emerge later? How would you perceive this situation? The glass was half-empty or half-full?
