When talking about investment plan for a family, the money is always for family, kids and couples. Families are people who directly include into your investment direction. Then, what about a single? There is no kid and no couple should be considered. There is also no family need should be concern. So, all things are so simple.
Thereby, it is the best time to use the money for investment since you have anything to worry. There is nothing burden you to get any profit sooner. Instead, you have more chance to increase your income.
It is tolerable if you want to enjoy the free time to spend your money alone. But keep on your mind, the longer the time you postpone the investment, the more time you lose for this best moment.
