Lol anytime my dude! There's plenty of options out there for you. I personally use vim for journalling and some other light text stuff, but that's a fairly minimal terminal tool. You can go that route, or you can grab Libre Office (Microsoft office alternative), or whatever else best fits your wants and needs. Like I said, my DMs are open if you have questions, but I do want to reiterate that I am not a professional, I'm just some dude who learned about this junk in highschool and has been using it as your average everyday computer nerd. I hope you not only learn a few things, but I hope you have fun exploring. If it doesn't work out, oh well, nuke it and go back to what works best for you. It's your computer, use it how you want to, don't let anyone else tell you otherwise.

One last recommendation before I hop off my soapbox, assuming you give Ubuntu a shot, I'd recommend checking out some of their different "flavors". They all work the same under the hood, but give you a different UI to work within. You can swap whenever, or run all of them, it's your call. I prefer Gnome (the G is not silent), it's Ubuntu's default, but there's Mate (pronounced like the tea, mah-tay), Kde (short for Kool desktop environment, no I'm not joking), xfce, unity, and more. Other than that, have fun!
