Drama about investing in another group coaching program

I have invested 8k in a 1:1 coach this year, 2k in 2k, 1.5k in hypnosis and invest in scholars monthly.
I now want to invest 2.5k in a marketing group coaching program.
I’ve had a challenging time around making offers/selling my coaching.
I have conflicting thoughts.
This program could help me with my marketing mindset. And all the best coaches say you don’t you need another coaching program, you need to manage your mind.
I fear that if I invest, I still will be in a struggle of making offers and selling.

C invest in marketing group program
T I haven’t master managing my beliefs yet, so this program won’t help me
F conflicted
A spin endless about the decision
R don’t make a decision or market my coaching
