Trajectory isn’t a word I use; it just isn’t in my vocabulary. Apparently it means “the curved path along which something (such as a rocket) moves through the air or through space,” but can also mean “a path, progression, or line of development resembling a physical trajectory, as in “an upward career trajectory.”
So, let’s think of it as a path. Sometimes you may have to change your path or trajectory slightly. 
10 Secrets to Changing Trajectory Today is a simple way to help think about where you’re going and how you want to get there. Sometimes, it may feel like your goal is far away: “Sometimes you compare where you are with where you want to be and feel defeated. Other times, it feels like your feet are tangled in the sheets. When dreams are big, progress feels slow.” When that happens, maybe you should try a different path.
You’ll get there!
