You can only get more in life by saying YES.
Relationships are like a book, in that they are for learning.
When you are doing what you really love and creating the life that you really want it will be easier to create a healthy personal relationship with someone that will be supportive of what you want too.
Not believing in something doesn't make it not exist.
You can't get more by going for less.
You will never see what you are capable of, although you must seek to.
