You are not alone and it is never too late. All you have to do is keep writing.
Just ask Longfellow:
It is too late! Ah, nothing is too late
Till the tired heart shall cease to palpitate.
Cato learned Greek at eighty; Sophocles
Wrote his grand Oedipus, and Simonides
Bore off the prize of verse from his compeers,
When each had numbered more than fourscore years,
And Theophrastus, at fourscore and ten,
Had but begun his Characters of Men.
Chaucer, at Woodstock with the nightingales,
At sixty wrote the Canterbury Tales;
Goethe at Weimar, toiling to the last,
Completed Faust when eighty years were past.
Or the New Yorker:
Just keep writing. Write free, write often, write without inhibition or self-censorship. You will get there.
