Time is the only true bartering resource. We trade dollars for goods or services but the hard earned currency for the transaction is one's time for another's. Due to the nonrenewable nature of this resource it is oft difficult for spare hours to be put into learning or researching that topic you always had a passing interest in or that everyone is gushing over. I try and keep an eye out during my daily experience for situations which may provide the excuse I need to allot time to one of the items on my "when-time-allows" list. On my list for some time: Python.
