Impossible Goal Question

I would love some feedback.
I’ve chosen my impossible goal to be to earn $200,000 by the end of 2021.
I currently earn $125,000, it will go up to $128,000 in May.
This is a big jump for me because I ultimately want to earn the extra $70,000 as a part time life coach, and I’m not even in the CCP program YET. I wanted to get into the Jan 2021 group which is sold out, so will be in the April 2021 group.
My question is…am I being to limited by saying how I want to earn the extra money as I create my goal? I started generating a list of ways to bring in extra income prior to certification:
Doing overtime work (I’m a teacher so can tutor, summer school, take on an extra class).
Sell things.
Thank you in advance for the help.
