Don't write yourself off, there are many ways to earn Bitcoin these days. Who knows maybe you earn that 1 Bitcoin quicker than you ever imagined and then you set your sights on joining the 1 in a million club and owning 21 Bitcoin.
Yup, I am as pessimistic as OP, thinking owning 1 bitcoin is impossible for me because my income is too low to think about. But life is full of surprises, even now, I own several bitcoins, not just one, which I never dared to think about. Let's stay optimistic and always try, everything will pay off.
