Have you ever walked in life for a while and everything was great but all of a sudden things changed. Sometimes things were gradual and you are not really sure what the true lesson is about. This is where you should stop and of course you will understand those feelings inside yourself.
I have learned in life to listen to my inner voice because it is usually right on the money and when I do this I am benefited. However, I being imperfect many times do not want to listen to this voice. So as I go along without this I have made mistakes and I pay for them later in life. The great thing about learning a lesson is simply because even though you take one step back in progress and then you go ahead with your next step! You are learning no matter what others say!
From this position you can accomplish anything. Learn from your mistakes!
My senses are awakened when I am by the ocean.
