Since updating Blender to version 2.91, I got kind of lost on how to scale a texture. Now, having said this, I do think I’m using this whole texturing feature wrong on Blender. I’ll have to really take some time off sometime to properly look into this, but for now, this works.
Anyway, in the Shader Editor (previously I used the Node Editor), I should arrange the nodes as seen in image above.

Thank you for checking out my Blender Note! I am by all means a beginner in Blender, so I do not feel qualified to label this post as a 'tip' or 'tutorial'. However, I decided to upload this note for myself, and hopefully it can be useful to others as well.
