You have a right to experience happiness right now, in the present. This is a very important concept to keep in mind. You don't need to wait until you accomplish your goals before you are happy.
Many people think, "Only after I accomplish my goals will I be able to be happy." These individuals mistakenly think that they need to wait in order to be happy. They feel that they can't be happy right now. They tell themselves that they first need to achieve what they would like to achieve before they can be happy.
But happiness is a birthright. You were born. You are now alive. You are breathing now. Right now you have a right to be happy. You can choose to be happy now.
