In case you're wondering, you don't conjugate the same way as Spanish or other similar languages: To Say - I say, you say, he/she says, etc... Also, to add on to Pascal Kim, after you change the tense, when you use it in a sentence, you have to apply the correct level of formality and/or honorifics. Someone please correct me if I'm wrong, I'm also still learning the language.

First notebook entry: Introducing myself

My company keeps pushing me to improve my English, but it is really stressful.  I thought it would be nice to meet a friend that could help me out. However, I can't just take an advantage of you, so if I can help you out as well, I'll be happy!
