Ellie, do you mean like putting a deadline on the intention?
I guess if this is what you mean then the answer is 'no' in my opinion. I have rarely heard anyone say that this is how it's done. However, if it's long term like intending to be a millionaire in 10 years or finding the right partner within a year, I would say this is fine.
Wanting £5000 in a week or the perfect house in 5 days will probably not manifest. However, and this is important, it's not clear to me whether this is because you just can't have deadlines
or it's because it makes it harder for you to believe it will manifest and therefore it doesn't show up. The key is that you believe 100% that it's on its way.
What you should do is to state the intention aloud and see if it is believable to you. If, for example, you say I will have xxxx in my life by xx.xx.xxxx and you feel deep down it can't happen then abandon this approach - you can always try it again later when you become an expert at manifesting
Instead try stating, "Infinite intelligence is brining to me the ideas, people and circumstances necessary to have xx in my life. I will act accordingly and bring this into my experience. Thank you" In my experience this is how I have manifested things. The attraction occurs mostly at the level of thought i.e. I get a flash of inspiration and then I must act on that. Having said this I don't rule out manifesting without action although I haven't experienced that yet. I don't put limits in the LOA
