Just because a good opportunity comes to you, Sagittarius, that does not mean that you have to accept it. You may find yourself in this kind of dilemma today or soon. You can see the merits of this chance, yet it is not perfect for you - either because of the timing, or the resources you need, or some other element that you can't change. However, someone close to you might chastise you for saying no. Don't let that make you feel bad or regretful if you believe you're doing the right thing.
