Sam, there is nothing wrong with reinventing yourself.  Human nature, as it is, tends to run out of motivational steam every so often, and taking a view from the outside certainly puts your priorities into perspective.  Things change, attitudes change.  As long as you can project your expectations into the future, or start afresh from grassroots, it should be a good beginning.  I wish you much luck.  I eagerly await to see what you can create.
