Next project

Not sure what the next project should be.  I am still casting around trying to figure out what I want to be when I grow up.  I'd like to go back to school, it is invigorating to be a student.  It is also expensive and takes a whole lot of energy.  I feel like I still have so much I want to learn.  I want to learn how to be a good instructor.  I want to learn how to use technology in the best way to be a good instructor.  I want to explore the creative part of being an instructor and designing learning opportunities.  How can I do this?  I am 56 years old and there is part of me that is saying that I am too old to even consider it.  What benefit would it have?  I am sure that I could do a better job if I knew more about instructional technology, designing e-learning modules, and just felt I had more time to devote to the tasks of devising library instruction sessions.  The days fly by and I am lucky to have 20 minutes of time in a block to do anything.  Don't know.  Still thinking.
