"In investing, what is comfortable is rarely profitable." — Robert Arnott

At times, you will have to step out of your comfort zone to realize significant gains. Know the boundaries of your comfort zone and practice stepping out of it in small doses. As much as you need to know the market, you need to know yourself too. Can you handle staying in when everyone else is jumping ship? Or getting out during the biggest rally of the century? There's no room for pride in this kind of self-analysis. The best investment strategy can turn into the worst if you don't have the stomach to see it through.

Don't despair amid the inevitable setbacks that all investors face, especially during a crisis in the market. If the reasoning behind the investment was sound, stick with it, and it should eventually turn around.

If you're a millionaire by the time you're 30 but blow it all by age 40, you've gained nothing. Grow and protect your investment portfolio by carefully diversifying it, and you may find yourself funding many generations to come.

"Financial peace isn't the acquisition of stuff. It's learning to live on less than you make, so you can give money back and have money to invest. You can't win until you do this." — Dave Ramsey

By being modest in your spending, you can ensure you will have enough for retirement and can give back to the community as well.
