Hi Sushi, i really dont think it would hurt anything if you incorporated it into your routine.
This is Lanie's advice to those having trouble visualizing:

"What if you can't clearly visualize the person? Please do not worry over this! I explain in my books that it doesn't matter. Just your intention alone is enough to connect with them. It doesn't matter if you see them, feel them, sense them, or just imagine them. It will work if you can't visualize at all! I get more emails over this subject than is necessary because there is no need to obsess over this detail. Just relax, use the technique and connect with them in whatever way seems most easy, natural and real. You can imagine their touch, smile, voice or anything else that endears them to you. It does not have to be a clear visual. The same if you close your eyes and imagine your bedroom. You get a general sense of what it looks like, where things are placed and how it feels. Same with your man! :-)"
