That is, moments of sheer take-off, career achievements and financial bonuses will be interspersed with periods of depression and a complete lack of motivation. Of course, all of this will affect your ability to work, so the first piece of advice from your celestial patrons is not to give in to doubts or decadent attitudes. Especially since in most cases these will be far-fetched ideas, without any real substance. On the other hand, towards the middle of the year and later on, you could develop natural delusions of grandeur. Of course, this will affect each person differently, but the result will be one and the same: a financial crash. Although it won't be so massive as to evoke tears, it will be tangible, and require you to forgo many things you want. For this reason it would make sense to get a grip on yourself, and if (or when) it becomes unbearable, you can approach friends, they won't turn you away. You should also pay attention to your desires, which in spring and autumn may not prove to be adequate, realistic goals, which you will pursue for a long time.
Likewise in 2018, Sagittarians absolutely cannot allow themselves to squander money. Nightclubs, partying with friends, quality rest - all of this is good, of course, but not in the year of the dog. Relax in a different way, this is realistic! For example, a trip to the forest, a campfire on the shore of a lake, with the chirping of forest birds - this is the best relaxation imaginable. If this seems strange to you, unrealistic or too pathetic, Mercury unambiguously indicates that you have serious problems with perception. This could be the result of overexertion at work. There could be a number of preconditions, but you won't figure them out without careful analysis. You will be able to pull yourself together, save money and learn a lot. Aside from that, in 2018 you would do better to avoid starting your own business, if that's something you want to do. Especially not with friends. Not because they'll let you down, but because it will be unnecessarily difficult for you, and too many external factors will be against you. You simply won't be able to achieve the desired goals, and you'll be disappointed. The best thing would be to stick to the middle ground - work for pleasure, and during your leisure time do something else, preferably with a bit of creativity.
