As per your horoscope, your career house and the house of gains are very potent and you are an excellent career woman. Can you let me know why you want a change now? I am asking this just because your present time is good and future also will remain the same upto 2018. What you wish to achieve by making a change may not materialise till then.
All your houses have good strength except the 2nd and 7th house. Read my blog http://navagrahastro.blogspot.in/ to get better insight into Astrology.
