As you read through threads you will often see ones that are unfinished. Many times the OP will offer an explanation, and other times it just sits there with no updates.
Some people will change their plans based on their situation, time money etc. those plans may cause then to end one thread & start another.
The issue you may have with this thread is that most people who do not have the time to finish a project, also don't have the time to find your question & reply.
Others find it too painful to rehash their situation, for example, loosing a house, divorce, financial issues etc.
