Rather than letting market shifts dictate new directions, take your cue from your own life. Develop contingency plans for every eventuality so you're constantly moving forward, whatever happens. And revisit those plans frequently, tweaking and fine-tuning them to match changing circumstances and situations. Either they become obsessed with their investments or they don't pay any attention to them. Neither extreme is healthy.
Perpetual planning is the happy middle ground.
Read one or two publications you respect, but don't watch CNBC 24 hours a day or ignore the financial pages entirely. Perpetual planning has been a part of Rob Bossart's life since he first started working. Now a partner in a New York law firm, he's still learning. In the past year, for example, I've spent a lot of time reviewing my portfolio to keep on top of what appears to be Wall Street's renewed recognition of the fundamentals. Do your best and leave God the rest.
