Two failed attempts is not nearly enough to throw in the towel. If it is, you are in the wrong business. Here's what Edison had to say when a reporter asked him about his "failure" when trying to invent the light bulb:
"Young man, why would I feel like a failure? And why would I ever give up? I now know definitively over 9,000 ways that an electric light bulb will not work. Success is almost in my grasp."
Then, after 10,000+ total attempts, success.
Stop whining, get comfortable with making some mistakes along the way and keep pushing forward. All it takes is one success to change your entire world. If you don't have the intestinal fortitude to do that and expect things to come easy...accept your fate, throw in the towel, work a day job like the "common man" and try and enjoy your life as much as possible.
