Act as if.

If you want a new phone, just go on about your day being excited and waiting for your new phone to arrive. Want a cat? act as if you already have one and its just hiding somewhere in your house. This method works the best for me at least.

make up convs in ur mind or play pretend w dolls

visualization, not even meditating but just daydreaming

thinking about desire as if you already have it (doesnt need to be robot affirming, or constant if you're lazy, can just be reminding yourself) :)
