25k in just 4 years is achievable.
believe me. if you have a good Degree from recognized Universities, good extra certifications, and also a good side "project" included in your resume, you can and you will.
I do have a Degree and MSc in Artificial Intelligent, and I do have CCIE and PMP certification. I have been sponsored by MARA under "SKim Pelajar Cemerlang" years ago. and for me, education and several professional certification can do justice for your salary.
Started my career in Garena Singapore 4 years ago as a Lead Developer/Programmer for BeeTalk Social Messaging Application. Within one year of its launch, BeeTalk has garnered up to 10 million users across Asia, and right now for 2015, 50++ Million users worlwide.
Before, when i started working for Garena, everyone asked me the same question, why Garena? and for me. it is not the company that will do the justice to you, but the project/product that you are working on that time.
For now, after 2 years in Garena, I am working with one of the best internet/tech companies in the world, been through 11 Level of "hell" Interview Session before being hired for the position. work hard and do believe in yourself. the more your salary is, the more bigger responsibilities for you to take care of. You Can Easily Enjoy Life In A Way Most People Don’t.
Cheers
