As with the weather at sea, markets can be unpredictable. A sudden squall can whip up waves of volatility, tides can shift and strong currents can threaten to blow you off course. Like a seasoned sailor, an experienced adviser will work with the conditions.
Once the storm passes, you can pick up speed again. Just as a sturdy vessel will help you withstand most conditions at sea, a well-diversified portfolio can act as a bulwark against the sometimes-tempestuous conditions in markets.
Circumnavigating the globe is not exciting every day. Patience is required with local customs and paperwork as you pull into different ports. Likewise, a lack of attention to costs and taxes are the enemy of many a long-term financial plan.
Distractions can also send investors, like sailors, off course. In the face of "hot" investment trends, it takes discipline not to veer from your chosen plan. Like the sirens of Greek mythology, media pundits can also be diverting, tempting you to change tack and act on news that is already priced in to markets.
A lack of flexibility is another impediment to a successful investment journey. If it doesn't look like you'll make your destination in time, you may have to extend your voyage, or take a different route to get there or even moderate your goal.
The important point is that you become comfortable with the idea that uncertainty is inherent to the investment journey, just as it is with any sea voyage.

That is why preparation and planning are so critical. While you can't control every outcome, you can be prepared for the range of possibilities and understand that you have clear choices if things don't go according to plan.
If you can't live with the volatility, you can change your plan. If the goal looks unachievable, you can lower your sights. If it doesn't look like you'll arrive on time, you can extend your journey.
Of course, not everyone's journey is the same. Neither is everyone's destination. We take different routes to different places and we meet a range of challenges and opportunities along the way.
But for all of us, it's critical that we are prepared for our journeys in the right vessel, that we keep our destinations in mind, that we stick with the plans, and that we have a trusted navigator to chart our courses and keep us on target.
