Correção de texto: Today is a good day

Hey, how are you doing? Today is a good day to practice English, isn't it?
It is midnight now, and I am wrinting writing a text to practice my English skills. I'd love to learn enlgish, English, sometimes it seems very dificult,difficult but another at other times it seems very easy. Actually I need to practice more time often, and soomsoon it will be very very easy. Courage and confidence is the key to go up in learn any subject and that's what I need.
Please let me know of my mistakes.

Thank you all. see you.

Parabéns, ótimo texto, poucos erros, e acho que todos que eu encontrei foram só falta de atenção mesmo!
Não mudei a essência do seu texto, mas vou deixar abaixo sugestões de como vc poderia escrever de uma maneira diferente as mesmas coisas.

"..and I'm writing this diary to practice my writing/English skills."

"I'd love to learn English, there are some topics I find to be very difficult/hard to understand, yet others are very easy..."

"Actually, I just need to practice more often and I'm sure it will get easier/and I'm sure I'll get the hang of it.

get the hang of something (informal)
to succeed in learning how to do something after practising it
