Use all your senses. I find techniques never work well for me, but activating and focusing on your senses works wonders. Perhaps it will help you out, perhaps not.

What i would say is try touching things and focusing on the texture, bend down and smell it as well. Focus on what you hear, and perhaps there is something nearby you can taste. If you cant find anything to do, rub your hands together real fast and focus on the friction and resulting heat.

Basically put your attention into the little details and it should help intensify the larger things.
