For objects, try imagining the object is behind you, and when you turn around you'll find it. For places, walk up to a door and say that the place you want is on the other side of that door. Just open it and walk through!

Don't doubt yourself when you're doing this, that just makes it harder. And if you're still having trouble, try using a magic wand to make stuff happen, a lot of people find it easier to make their power go through another object first. (And you can act like Harry Potter! )
