If you win at gambling the first time, you always think you can get your money back after you lose. If you get bitten by a dog the first time you try to stroke one, you will be frightened of dogs. Until you have enough other experiences to convince you of the contrary.
Just because you keep trying doesn't mean the universe owes you a success. But it doesn't mean that because you failed at everything in life, you will fail at the next thing either.
And keep on trying.
What is the alternative? You weren't put on earth to stay in bed.
