You may be focused on your social life as well as spending a lot of time with your family in the early months of 2016, but that doesn't mean you won't be putting in the hard work that is needed for you to get along in life.
Mars is in Scorpio from February 20th, and suggests that you will be working harder than usual at this time. This might mean more hours at the office, or more work to do when you get back home. You might feel that you are not really getting much back for your extra efforts, but if you keep working hard this will soon change...
The Sun moves into Pisces on the 14th March, and then onto Aries on the 14th April, and this graceful movement will see recent efforts well rewarded. You may see a pay rise, or just the benefits of your overtime, and you will also be recognized by superiors at the office as being a really top employee. A fateful event could bring you yet more success; perhaps by landing you a new client or deal.
Towards the end of May, people might become jealous of your achievements at work. Venus moves into Taurus on the 20th, and you could feel a funny vibe from coworkers. You should be very diplomatic at this time, and sometimes it is better to say nothing at all. Even an innocent suggestion could be taken badly.
Apart from that it will be all systems go in your career, and you will be plodding along and doing well. If you are not enjoying your current job at this stage, and feel unrewarded for efforts, Jupiter gives you the opportunity to change to somewhere preferable when it enters Virgo on the 13th August. However, many Sagittarius will be happy with their current situation at this time.
Towards the end of August, work loads start to increase, and you will see much more pressure coming your way, either from those above you who are demanding more, or from extra demand in your own business. Venus and the Sun conspire in Virgo to create this challenge, but if you learn to thrive, and use the pressure as extra motivation, then you will be well rewarded at the end of September. Expect a bonus or promotion of some sort!
It will be hard work that sees you advance this year, along with composure in the face of any conflicts. Keep your cool and keep your head down, and you can expect to move forward in business or work.
