So I would say work on your 'eye' first, and there are few ways better to do that than shoot, shoot, shoot. Start getting your 10, 000 hours under your belt. Get out there and look for ‘the moment’ and use whatever you have on you to catch it. If you're not happy with it, delete it, but the mere act of shooting it will build photographic muscle reflex in learning both to see and capture.
And the tool to help you learn how to see, and which gives you permission to capture 'carelessly' and often, is likely sitting in your pocket right now.
For those who I know will be interested, I shoot on an iPhone 4 and my go-to editing apps are:
Snapseed and PicsPlay Pro for more controlled editing.
Camera+ but only really the amazing ‘Clarity’ function.
Facetune for basic retouching.
VSCO Cam to add some vintage film tones.
Mextures for light leaks and destressed effects.
