It is easier to access your intuition if you are quiet.
Later on, when you get really really good, you may be able to access your highest guidance even in a crowded room with lots of people. You have to be really centered in yourself, grounded to the earth and connected to Source in order to do that.
But to develop your intuition, you will need a lot of quiet time.
You may think you are getting a lot of rest or a lot of solitude already. However, you may be surprised to learn that you need to slow down even more if you are going to be able to really listen.
If you are not able to access your intuition, that is a good sign that you need more quiet in your life.
