There is a unspoken belief generally held that when we are following our heart's desire that we will be swept away by rapture and all things will become enjoyable.
Nothing could be further from the truth. We will still need to take out the garbage, change the diapers, sit in the local parking lot called rush hour. pay bills and so on.
Life continues while we are fulfilling our quest and we must meet it's demands no matter how petty or time consuming they may be. It would be nice to have a magic carpet to whisk us away from the mundane and bestow the gift of success without dealing with what has to be done.
When we are looking for that magic carpet and ignoring all other opportunities that would involve doing some things we don't like doing then we will fail. Which may be why so many people never embark on the journey that would create the dream they have.
After a while we can get in the habit of only looking for the impossible and so end up at the end of our life not having tried anything.
