New To Creating Models

I am working a day job that I need to keep while I am building up my side hustle. Because of this, I sometimes miss replies to important emails. I discovered that today and lots of fears came up:

C – forgot to reply to a good potential customer for over a week
T – Iā€™m so bad at this job right now
F – fear I lost the business for good and boss will find out
A – immediately reached out and apologized for delay in responding
R – ???

I am new to making models and am struggling to create the new model with the new thought.
