Might be something very GREAT BREAK THROUGH is waiting for you. These all incidences are creating the path for that BREAK THROUGH, because if you did get success in any of your attempt (you mentioned) then might be you would not have attempted the other one. But you did and even if that one failed then you again did. So clearly you are moving towards to your GREAT BREAK THROUGH .Keep trying because the day you get what you deserve and what you good at then you will be the BEST in that. Nitin T
