Correção de texto: Today is a good day

Hey, how are you doing? Today is a good day to practice english, isn't?
It is midnight now, and I am wrinting a text to practice my english skills. I'd love to learn enlgish, sometimes it seems very dificult, but another times it seems very easy. Actualy I need to practice more time, and soom it will be very very easy. Courage and confidance is the key to go up in any subject and it is what i need to.
Please let me know my mistake.

Thank you all. see you.
