Interesting thing about reading our own cards is the frame of mind we're in when we read. One day for example you may feel exhausted, doubt your abilities and wonder if your proposed plans and business will ever take off. There's chaos around you and you feel unable to cope, the cards will mirror that mind-set and energy and the chances are the outcome will not look favourable.
Following wk you've caught up on your sleep and your studies, you've strength in reserve and your self belief is strong, you lay the same spread and success is predicted as the outcome.
This is because everything in manifestation is born of thought energy, we lay our path with our thoughts both conscious and sub-conscious which are subject to change at our free will which will then be reflected in the spread. If we're not in touch with what we're thinking we're certainly not in touch with what we're creating.
Hence it seems we are able to change our future (what we're drawing to us under the law of attraction). Cards reveal where we're heading with our particular mind set. Basically self knowledge, attunement to our conscious thoughts and understanding the nightmare sub-conscious ones in the realm of the moon that usually account for negative cycles is the key to steering our life towards where we want it to go.
Would the 1st or 2nd reading be correct? I think both would be correct at the time of reading. There's the future as it stands or the future you can choose through inner work. I don't believe anyone's future is set in stone, rather in mind stuff and the cards are never wrong but we must learn to read them correctly and understand the fundamental principles of the spiritual laws upon which they are based
