Things happen faster when you let go and be patient. If you keep worrying about it, you are thinking about lack. if you let go of it, there's no resistance. What's there to block you? I like the example of gravity that Supernova gave us about the plane notion. we can still fly planes despite gravity. Otherwise without gravity we would keep ascending into the depths of space! The same way, you can attract nothing despite LoA actually attracting it for you.. Adding to this, there is still the force of gravity acting on the plane but the net resultant force is upwards. The same way, you think the law of attraction won't work for you but in fact it's the law of attraction giving you the stuff that is needed in order to change your mindset that it will not work for you and hence go to the default issue that many people have. You have the thought that it doesn't work for you. However, if you change that mindsetby looking for proof that it does, you will see that the law of attraction helps you MUCH MUCH MORE.
4) Hmm... weird again. Dunno what books you've read, but that is totally false. Nothing is perfect and the "LoA" I subscribe to doesn't say what you've described. Visualizing is only one tool of LoA... one which I don't really use. The perfect relationship and perfect diet are total BS. you don't visualize those things, you either build them (a good healthy relationship, not a perfect one) or follow them (a good diet).
I used to do a lot of work helping people to stop smoking. There are only 2 reasons people don’t stop smoking. One, because they don’t want to (often this is subconscious) Two, because they don’t believe it’s possible. Or they assume it will be incredibly difficult and painful, and they can’t do it without suffering forever. (Again, this is often subconscious and it is a flawed assumption).

As well as offering practical guides to using a wide range of generally applicable exercises that enable you to use the Law of Attraction in your quest to get what you want, we will provide details of more specific exercises that target specific domains. After all, the exercise you might use in a search for prosperity differ from those that lead you towards romance, and from ones that focus on career goals. We’ll also give you suggestions for ways to create your own exercises based on some of the affirmations and visualizations you've already developed.

Acceptance. The next principle of conscious manifestation is acceptance. I don’t mean giving up or attitude saying ‘whatever’. What I’m talking here about is acceptance of your new belief and that it’s true for yourself and you can have it. Just accept that it’s already yours. Don’t focus on reasons why it shouldn’t work out, instead surrender yourself to your desire and fully accept it in your life. Accept that this is what you want and that you want to have it.
