User: First day of baking with sourdough
Assistant: Today is my first day baking with sourdough. The process seems very time consuming as you first need to create a sourdough starter. Creating the starter takes usually seven days. 
Following baking instructions can also be challenging as you need to be very careful and make sure that all ingredients are added in a certain order.
There are many different kinds of flour, all with their own baking characteristics, making the process even more difficult. 
I am nervous about this, but I've always wanted to learn this craft as baking with sourdough has been done since the beginning of humanity.
