Hello and blessings,
I want to second what Sandy said about deadlines and detachment. While some may be able to do it, a firm deadline could be a source of anxiety for a lot of people, which will sabotage their overall efforts. I have a friend who wanted to manifest a large sum of money by a date and failed. When he went back and reflected on it, he realized the date itself had been a negative one for him based on his past. He let go of that or any date and ended up manifesting the money a short time later. I'd be interested to hear from people in the forum who have successfully set a date and how they did it.
