The sharp declines and rallies within the stock market so far in 2015 are enough to induce nausea in anyone unwise enough to follow them too closely, notes David Fish, editor of Direct Investing.

Even worse, the resulting bouts of sadness and elation are signs that a person is simply investing emotionally or committed to the role of a trader (or speculator), rather than that of a long-term investor.

The cure to this state of self-induced manic depression is a healthy dose of high-quality dividend-paying companies and a conscious decision to exercise patience and let compounding do its wonders.

If you're still in the accumulation phase, practicing a dollar-cost averaging approach should help to avoid the worry that comes with investing large sums at what could be inopportune times. In other words, the cure is all in your mind.

Founded in 1885 and listed on the NYSE since 1944, Johnson & Johnson (JNJ) is a major healthcare products company whose sales totaled $74.3 billion in 2014, with over 50% coming from foreign sources.
