Keep pushing. Do not let the rejections or any failures discourage you or make you feel less worth. Keep your eye on the big picture. It is okay to take three steps forward and one step backwards!
"As an inventor, Edison made 1,000 unsuccessful attempts at inventing the light bulb. When a reporter asked, "How did it feel to fail 1,000 times?" Edison replied, "I didn’t fail 1,000 times. The light bulb was an invention with 1,000 steps."
