Of course, it’s going to be a doozy.
What first step wasn’t a doozy?
What thing did you ever start for the first time that the first step wasn’t the hardest?
The first time you walked.
The first code you ever wrote.
The first bug you ever worked on.
If it wasn’t a doozy, it wouldn’t be worth doing.
And if it wasn’t a doozy, it wasn’t something new.
