2) Get Closer
Whatever lens you start with, go longer or move yourself (zoom with your feet) to get closer to your original subject.
Say you’re shooting a landscape with a mountain and a foreground using your 24-70 mm lens. Zoom in to the longest focal length (70mm), or switch to your 70-200 mm lens, or step several paces forward and start looking for compositions. That’ll help train your eye to see in smaller sections.
I found this vine trailing down a shaded wall when I was strolling through town in the middle of the afternoon. Walking closer, I was able to isolate just a small section of the vine.

It doesn’t have to be a tiny plot only a few inches square to be intimate. The telephoto can also isolate a section of a much larger landscape, as in this view from Zabriskie Point in Death Valley. From the viewpoint, you see a series of soft, rolling hills and canyons. I wanted to isolate the trail from Golden Canyon and the lone hiker. That gives the scene a more intimate and human scale and feel.
