As far as I know, the simple present in portuguese can refer to something that is happening right now as well as to something that happens usually/regularly/once in a while, and I think the gerundium is a rather informal way of speaking. Can somebody confirm or correct me please? :)

Circumstances play like scales in music,they tell you when to emphasis or not , so to not say or translate something else at the place of another. Figure out quickly theses circumstances help a lot for the intonation in phrases. And very importantly listen to native borned when they're conversing and if you can/ whit permission engage yourself for pratice. Do not be embarassed or embarassing, be natural always polite and smiley. Start with short phrases then the confidence will come. Take this moments like golden! All my best.
