Believe in your unique abilities and skills. Your career path isn't defined by the number of job rejections but by the perseverance and determination you show in overcoming them.
Remember, every 'no' brings you one step closer to a 'yes'. Each rejection may be disheartening, but it is also a learning opportunity that brings you closer to your dream job.
