Isn't it sad to go to your grave without ever wondering why you were born? Who with such a thought would not spring from bed eager to resume discovering the world and rejoicing to be part of it?
I suppose if you look back to your early childhood you accept everything...
I had never felt so lonely and so sad in my entire life.
Whatever it is you want to do take a job in that field. You will learn by experience and slow and steady you'll get it done!
