That's a good idea. I have been trying to find time to write down my ideas, feelings, and thoughts as much as I can..
Sometimes I have ideas for new products, just random things, and I will write a note on my phone as to not forget because my days are usually very busy. I can save them as a note on my phone, and elaborate later when I'm not so involved with work of whatever.
Great post!
I'll talk about this in my next post, it's all about making it a routine to when you decide to write your journal. For me I typically write it at the start and at the end of the day. I bought a really nice, thick, beautiful (well, beauty is relative) book so I can't possibly carry it around with me. But whatever random thoughts, ideas etc I have for the day, I'll make sure I transfer them to my journal before I go to bed. The key is making it a routine
