To get yourself into the “business” of taking images for your personal use, start here:

… and ponder on the points thoroughly.

I’ll add three more points
a) You have to bring the camera WITH YOU to be able to catch those special moments of life
b) You have to be proficient with the camera you have at hand
c) most, if not all, cameras as of 2015 (or even earlier) take very good photos – given a) and b)

Learn the basics; Aperture, Shutter speed, ISO:
all else is just icing on the cake; tools on top of it.
