GO FUCKING PUNCH SOMETHING..... and then get back to work heading towards where you want to be. As others have said, the truth about success is that it is hard work -- even when you are doing everything "right". And hard work is always hard work.
Blow off some steam and then get back to work. You're in good company:
** Robert Goddard designed two hundred ideas for rockets before he got one to fly into space.
** Henry Ford went bankrupt five times before his automobile manufacturing idea started working
** Fred Smith was giving a failing grade by his Yale professor because his idea for FedEx “wasn’t feasible”.
** R.H. Macy went broke seven times before his clothing store caught on in New York City.
** J.K. Rowling shopped her book thirteen times before a publisher would take a look at he first Harry Potter book.
Get back up and keep trying.
