It's really tough to sit still and ride out the storm in the midst of choppy waters, but before you decide to abandon ship ask yourself if you've REALLY given yourself enough of a chance.
Have you really waited it out long enough?
Have you really done everything?
Have you really believed in yourself enough? and for long enough?
Have you really set the conditions for you to succeed?
Have you asked for help?
Have you really tried?
Something when things are working it's not because you're doing something wrong, it's simply because you just haven't been doing what you need to do for long enough. Impatience can KILL the realization of the dream.
