Hey, I wish you fun and adventure. Practice, practice, practice. From my perspective, maintaining a strong desire and firm resolve are helpful. It is essential to center yourself and work from within the comfort of your center.
Centering is to be focussed at the spot within you where you feel peace. It is the place where your energy body connects to the physical realm and to the physical body. (i don't know why, but for some reason, men usually center just below the breast bone and women center just above the belly button.)
Sit in a chair. Don't lay down as it's too easy to fall asleep.
Ok, once centered, imagine you are standing a few feet in front of the resting body. You are IN the part that stands up. If you turn and look back at yourself, you might snap back into the body, so it's better to ignore the "old sack" in the chair and just maintain your identity with the free-to-move self. Move to another room, or step outside. Just BE in the other room or outside by wanting it and don't bother going step by step. Doors and walls are not an issue to the astral body, but they are to the mundane mind. So you don't want to deal with mundane matters. It makes the mind reconnect to the physical form.
Another way is to desire and resolve from within center to be at another location. Your center is everywhere all at once. So it's the link to any place & any time.
