Don't start talking to God when you're expecting the kids home from school, or your waiting for an important phone call.
You need to be relaxed, disconnected from the outside world as much as possible, and able to focus your thoughts on talking to God.
A lot of people find that talking to God first thing in the morning works for them, before the hustle and bustle of the day really kicks in. Other people prefer to do it later at night, when most of the rest of the world are already in their pyjamas.
You don't have to talk to God at the same time every single day, but scheduling your talk to God session in advance can really help you to stick to it, especially at the beginning.
The single biggest thing that's going to make it hard for you to talk to God is your cellphone (especially if you have Whassup!) so, turn your cellphone off! The world can get by fine without for a few minutes, and nothing bad is going to happen.
(That's one of the first amazing things you learn when you start talking to God.)
