That is called learning. No need to be sorry.
"took me a about a day to find out how to do it."
Same. When I started using 3ds Max 9 in 2015, it basically took me a day to get a texture up on a simple cube.
Any modern modeling program is like that, really.
It's a different philosophy from Hammer, where you simply right-click a face in the Texture tool.
Meanwhile in modeling programs, you create a material, give it an image, and apply it.
Furthermore, you don't have the Select tool, you don't have the Clipping tool and whatnot. Instead, you got a different set of tools that are suited for both organic and anorganic geometry, so you got functions like Bevel. In Hammer, you'd have to use the Clipping tool, then cut the edge off diagonally. If you wanted it to be smoother, you'd have to cut the edge multiple times. Meanwhile in Blender, you select an edge, use Bevel, and set the parameters, like how many cuts, how smooth, you get the point. Combined with Blender's hotkeys, it's a pretty fast way of modeling things.
It is that different philosophy and way of thinking, which you have to learn. Once you're over that obstacle, you'll be skyrocketing in modelling.
