There are many different kinds of spreads that reflect possible futures.
I like to see life as a river. Every river flows in one direction: from its source to the ocean. Tidal estuaries might reverse their flow occasionally, but never very far inland.
In the same way, a predictive reading (as opposed to an analytical reading) will show what's very likely to happen in the future if you don't change your circumstances (ie, if you are a hard worker and the cards show success, then you stop trying because you think it's going to happen anyway, it won't, because you have changed the circumstance of being a hard worker that the reading's result was based on).
If you like what a reading shows you about your potential future, keep doing what you're doing or do it even more enthusiastically. Also, most "happy" cards will generally imply things you can do in terms of real-world work to bring about good results. This is still a matter of either floating downstream with the river's flow, or swimming downstream.
If you really don't like what the reading warns about in the future, like any swimmer, you have the option to change your choices and change your direction, to swim upstream. And like real swimming in real flowing water, swimming upstream requires more effort, but can be done.
I find even predictive readings are about showing you the best you COULD achieve and telling you what you need to to to achieve that, and warning you of any risks in the future and telling you how to avoid or minimise them. It's always about enabling you to improve your life, not about taking a static photograph about some kind of "destiny" that you are somehow so powerless that you can't change it.
