Career Choice in 2015. Birthday on 23 Dec 1983

Hi. I have been doing the same works in the passed 5-7 years without much progressing in my current job. Avg 5% increment in annual salary, no bonus passed 2 yrs. Job title remained. I felt a bit loss of motivation/aim. Currently working as a design testing engineer. Thinking should I change my job to other industry, such as sales/marketing/banking or insurance agent.

Please help as my monthly commitment/expenses goes higher with age grow older (family, house, etc).
Thank you.
