Quarterly goals/business model (BL)

Hi! I just watched the Business Models video in How to Be an Entrepreneur. The new thought I’m working on believing this month is that I can earn $100K in my business between now and March 31, 2019.
I’m still working 3 days a week for my regular 9-5 job, and I am planning to leave in June. I’m thinking about structuring my quarterly revenue goals so that they build:
Q1: $10K
Q2: $25K
Q3: $32K
Q4: $33K
My reasoning is that I’m still building up my business, gaining confidence, and creating assets (courses/programs). Does this make sense? Or should I strive to hit $25K in my first quarter?
