You could try printing off prayers or saints' quotes and posting them in prominent places. Try on the bathroom mirror, on the fridge, above or beside the computer screen and other places where your eyes fall frequently during the day. It doesn't have to be long, just a little something that lifts your mind to Him for a moment.
I think it is normal for most of us to need reminders. As we grow in love for God we will automatically turn to Him more often during the day. There are saints who converse with Him at all times but we aren't there yet. We have to start somewhere. :)
The more we ask for His help, the more God will give us the grace of always being aware of His presence, even if our minds aren't actively thinking of Him at every single moment. That's also why the Morning Offering is so important.
