something that may help is to run through a meditation exercise before attempting to project it goes something like this
out loud say " i am going to put my self in to a light meditation"
then count in your head until you hit some number between 10 and 15
then say "i am now in a light meditation, i will now put my self in a heavy meditation"
form there count upwards from one until you reach some number in the teens, the catch this time is to visualize the numbers as you say them in your head, once you have done that visualize complete emptiness around you and TADA there you go
let me know if this helps you cause it always does for me
