I have three proposals in preparation right now, and I am starting to plan a fourth. I've noticed that it is harder for me to think of new and interesting projects lately, but not all the time. After attending a meeting, I am bursting with ideas. I just need that exposure to new ideas and new experiments to get my own creativity flowing. I know some people rely on their students and seminar attendance to keep themselves current, but that just hasn't been working for me. I clearly needed to make a change, and I think I found a solution (for now).
Using an RSS reader to read journals has been a revelation. It is much, much easier to skim through and click on what I want to look at in small time blocks, since I don't need to get through the whole contents in one sitting. Now that I am "caught up" in the feeds, I mostly see the ASAPs, which come in a few at a time instead of with a firehose of new stuff all at once. To anyone else who is struggling with this problem and hasn't tried RSS yet, I highly recommend it.
