How to pick the first "one goal" for my monthly workbook?

I am new in scholars and I am trying to follow the monthly workbook. I have difficulty picking the one goal to begin with. I actually have several goals that I want to achieve this year and I feel like having the same problem in choosing the priority to spend my effort and time in life/work. Is there some good advice and guides in how to pick a goal to begin? So that my start in Scholars could be easier and helpful to the future?
Thank you in advance for your reply.
