By believing it exists you create it, so you are not lying to yourself. And as soon as you imagine it you create it on another level, so again, you are not lying to yourself when you believe it already exists.
You create it in the future as soon as you believe it, and since all time is now, manifestation will be experienced when you catch up to it in time.
When you picture it vividly, feel it and state that it exists with affirmations, you create it. For best results do this once or twice a day. Spend a few minutes each time you affirm and/or visualize.
It is okay to focus on what you want. Constantly thinking about something will cause it to manifest. However, concentrated visualization, in which you believe you have what you want, is known to be very effective if it is done intermittently. Once or twice a day works very well. About ten minutes each session is enough.
