No Português temos o sujeito oculto por causa da conjugação dos verbos. No Ingles nao tem uma conjugação "formal" como no Português .Logo, você tem que repetir o pronome seguido do verbo para indicar quem é o sujeito ativo da ação.

Oi🇧🇷 You indeed can omit the personal pronoun 'I' in certain informal contexts. For example, when you are on Twitter you can safely publish a tweet with the following structure: 'Gonna watch Star Wars: The Rise of Skywalker with my friends tonight'. As you can see, in the example given there was an omission of the personal pronoun 'I' plus the verb to be 'am'. But if you are still learning the basics of the English language, I definitely don't recommend informal writing or speaking. It's fundamental to learn the proper way of expressing yourself in English first. Do you utilise social medias to enrich your skills when it comes to your target language? Twitter is a massively helpful tool in terms of making you absorb both the formal/informal writing in a short-term period of time, especially you if you spend a bit of your time on this social media on a daily basis.

Se não houver mudança do sujeito em inglês, não será necessário repetir o pronome duas vezes. Exemplo, ~(I went to school and later met up with my friends.)
