I, too, am a terrible trader. I want to be a buy and hold investor but that has caused me to ride too many positions to zero or near there.
So I treat every position as a trade and let the ones that work become investments. The market finally convinced me that controlling my losses was more important than maximizing my gains. That took a while because I appear to be a slow learner.
I take your advice as freely given and nominally value it at cost. ;-)

Rick
