Journaling

I am having a hard time finding things in Boice that seem to fit with my writing of poems.
I think his idea of journaling is quite important because goodness knows how many important moments we forget. I realize this, but too often I am guilty of not keeping notes and instead depending on my memory. When I go on a trip there have been times when every evening I would jot down notes in a journal. But what happens to the idea that pops up in your head in the middle of the night, or when your swimming, or taking a walk, etc. I often heard writers tell me that they carry a pad of paper or something just so they may record these moments. I know I should do the same but I don't.
Boice talks about reading other authors and talking to other people. This is new to me but I did like  his suggestion to use others that write in a similar genre to help you build a reading list. His points about pre- writing and the imporatnce of the time you spend took me back to playing basketball. Your likely not to perform well in the games unless you practice well. But a poem sometimes is a fleeting moment, so it doesn't a lot of times seem to apply but it for sure applies to most other types of writing.
