Mojo seems a common problem with this hobby, all of us suffer from time to time. People fall into three categories:
1, a 6 month fad , spending lots of money, getting frustrated with their results and moving on.
2, a 4 year stayer, who drifts away then comes back in various stages in their life.
3, a lifer who loses mojo for a month or so then is back with a passion and love for the hobby that never leaves.
