Well, 2015 is commendable year for you. A promotion in your career is expected, just work hard as usual and keep a good relationship with your colleague as well as boss. Don’t sleep very late. A good rest is needed for you to keep fit. And always remember to keep exercise, which will help you to have full energy in your work.
For purchase / construct house, the best time would be in Apr. May, and Jun. especially in the day of 28.
