I had this problem in the past, always chasing my tail. A few yeas ago I fashioned a grand, sweeping plan to change my situation and decided to carry through with it. The plan was very specific and required a specific order of events to materialize. As the years went by, certain of these criteria collapsed or were no longer viable. It was necessary for me to adapt the plan to new circumstances. I did this many times, as certain parts of the plan would collapse and new methods of compensating had to be found. I must admit that luck played no small role, but it seems that the plan will work, even with all of it modifications. So, rather than optimizing, I merely adapted, and hedged my bets at every new twist.
