When I took Dr Claudia Welchs' post graduate class, she came to conclusions a little differently than the way I was trained. At California College we were taught to break the diagnosis into many parts, reviewing the symptoms one-one and then finding a similar thread for the starting point - the digestive system.
Dr Welch, when overseeing our assessment of our clients, looked for what she called the "elegant diagnosis", meaning the core root issue that belied all others. She pushed us to get to the crux.
This form of whittling down is beneficial for many reasons - it simplifies the process the mind needs to go through to create a relationship with the disease, it makes the inclusion of the remedy in your daily life possible (busy, busy, busy), and it focuses our attention to one point to meditate on thereby reducing Vata dosha in the form of dispersion.
Practise - write down all the things that feel out of sorts for you. Look for similarities and find a central theme.
Find the core - now look at the opposite remedy or find the core and just observe - do nothing.
Depending on your viewpoint. ;)
