Borrowing makes time your enemy and adds emotional pressure. Invest in quality. Don't use a short time frame to define success or failure. Focus on a long-term strategy. Periods of difficulty, negativity and confusion usually represent long-term buying opportunities.
Bull markets ignore bad news and bear markets ignore good news.
In a negative environment, look for the underlying positives. Problems eventually get resolved. Use a professional adviser you can relate to. What you're really doing is buying into a company when no one else likes them. Sometimes after that, they really don't like them.
