Most seeds never grow. For 1 apple tree to bear 500 apples, you need 10 seeds. In life, this principle might mean you'll need to attend 20 interviews to get 1 job, talk to 50 people to sell 1 house and meet 1000 acquaintances to have 1 special person IF WE REALLY WANT TO MAKE THINGS HAPPEN, WE USUALLY NEED TO TRY MORE THAN ONCE. That's the law of nature. Don't take it personally. Just understand and work with it.
