A useful structure English cannot copy directly. Instead of a word for thing, Spanish puts lo in front of the adjective.
lo interesante = the interesting thing
Lo interesante es que viven aquí · Lo interesante es que viven juntos · Lo fácil es que vienen juntos · Lo complicado es que vienen juntos
Take that lo and add de, and you get a phrase used constantly in Spanish. Treat lo de as a unit.
lo de la fiesta = that thing about the party
Since de can mean about, it is literally "it about", that business about.
Lo de Juan · Hablamos de lo de la fiesta · No quiero hablar de lo de Juan así · Quiero organizar lo de mañana
For about you can use de, sobre, or nothing at all.
You could say de esta forma or de esta manera, but there is a far more common word.
No hablamos así · No comemos así · No vivimos así · Pero no quiero organizarlo así
De esta manera and de esta forma are still available if you want to be more emphatic, but así is what you will hear all the time.
Junto agrees like any adjective: juntos for them, juntas for a female group. To facilitate is to make easy, which is how you reach fácil.
Asked for they come, the student keeps reaching sideways for the irregular I form, saying "I might as well remember it". The teacher pushes back hard: that is how you get lost.
You need to be comfortable with a level of uncertainty to learn a language. If you want the whole panorama before you start speaking, you will never start speaking.
Sooner or later you will want to say the thing that distracted you, and in that moment you will sort it out. The more you do that, the more of the panorama you control.
One occasion in the whole language, and it is the present "we" form.
Hablamos · Comemos · Vivimos
Everywhere else they share endings: come and vive, comen and viven.
¿Dónde viven?
