I'm new to DSLR - 3 months - and found it like learning to drive- then I didn't have enough arms/ and or /legs to do everything- now I don't have time to think of everything. I was touring while teaching myself about my camera, so many shots were 'on the grab' To help me I set my exposure to 1/125th as my default, then my only variables were aperture and perhaps ISO, which I could generally cope with.

When I, or my subject, was static, I could think about full manual.
When I had the time I took the same shots on Manual, TV and Auto - it was interesting to compare them - so I am walking into Manual settings instead of Jumping
