You know as well as I do that in life we have no dress-rehearsals.
That is why you owe it to yourself to make the most of life. Since you only have 1 shot at it.
You might believe that you could come back for a second try, but the reality is that you have no idea of knowing that. As far as facts go, you have no dress rehearsels!
So, let me ask you this one question: Since you have no idea of knowing when this life will come to an end, can you afford to waste precious time doing things that you do not enjoy, waiting for that magic tomorrow when your ship will come in and you will start living the life you've always dreamt of.
