Struggling with weekly and daily goal setting

[Austin Works]

I am on my 2nd attempt at using the 90 Day Journal published by Biggerpockets, and I just cannot seem to consistently come up with appropriate weekly and daily goals to bring me closer to my 90 day goal. To be specific, my goal for this 90 day period is to increase my gross rents to a certain number, but I cannot come up with the smaller goals to take me there. Has anyone else struggled with this? Any examples of how you are setting your goals?
