This is indeed a good start to check on your life and have the general view. The only mention is that it's ok not to have all the area developed in the same time. Each of them is part of an evolutionary level and they come in time. We can feel complete even if we don't invest energy in the most "evoluate"ones like spirituality, for example.
You're right, we don't have to develop all sections at the same time, but it's important to maintain a balance.
