Salary feeds you every month and pay your bills.

However, bear in mind that salary makes you happy at the end/beginning of the month only and job interest keeps you happy when you work. I myself have took a job which I didn't like for the sake of money and found myself happy only on the 27th of each month (pay day). That's a really sad way to live your working life.

However, your interest should be reasonably realistic and the salary must be at least sufficient to meet your needs. The right choice should be a balance between salary and interest.

Pay could be a very short term thinking. Everybody wants more money, but sometimes, if your are in a job which suits your interest, you will love your job (but not nessecarily the company) and you will also become better at what you do, and eventually you may be more in demand.

If you can do a job you don't like really well, then you can still go far. However, most people will become better, happier and more motivated doing something they like and this kind of people may have a better chance to climb up the ladder. Salary can change in a blink of an eye once you found a higher paying job, but years of experience and knowledge takes time.
