Hey Christine don't worry about timing. Whenever you have time is fine.
Meanwhile I'm wishing I hadn't said anything about "soul", but now I have I'd better explain a bit more where I'm coming from.
The point is that most poets are chock full of emotion and they just love to and want to convey that emotion onto paper. The problem is that it's easy to feel the emotion, it's easy to know what you want to say, but it's not so easy to convey it in an interesting manner to other people. That's where the skill comes in.
What's happened is that over the centuries certain words and phrases have become used in the same way by countless poets to the point where they have lost all their impact.
I daresay that when the first poet to use the word "heart" to mean a deep and meaningful feeling all his readers went "WOW, what an awesome metaphor".
Over the years however the metaphor has become tired. Sure it still stands for a deep feeling, but it's not specific. One poet's heart is exactly the same as another poet's heart to the reader. Sure the poet herself knows her emotional state, but by simply using the cliche "heart" she tells her reader nothing about that actual state at all.
So your task as a contemporary poet is to find new ways to convey the specifics of your speaker's emotions. And similar considerations apply to the other words I mentioned.
I hope this makes some sense. I'm a little tired right now, so I might not be totally clear.
