Absolutely.
I am a huge proponent of doing tests.
Pick a lens and go out and shoot with it for a day, edit, grade, and export it, then watch it over and over again for a week or so and see how it makes you feel. Do it again. Do it with a different camera. Do it with a different technique.
Pick a sequence of 5 shots and then shoot that sequence with several lenses, edit the sequences together and then compare them.
Shoot a latitude test (the same shot but with each at a different exposure) and then work out how to grade them in post to match the shots. This will check if you have your colour management setup correctly, and will also show you the limits of your camera.
Take a series of shots and lower the saturation on all of them, and duplicate the shots many times in a timeline. Then test every method you can find to raise the saturation again, label and export them. Over a week or so look at them, compare them, see how each makes the footage feel, makes you feel.
Take the same series of shots as above, but try every LUT, try every method to add contrast, every way to apply a tint, every way to change WB, every way to add a split tone, every way to sharpen, every way to soften, every way to grade. Test every look.. film emulation, VHS emulation, etc. Test every resolution. Every way to add grain. Every way to reduce noise. Every aspect ratio.
The goal is to learn how to see.
