Many people have a lot of debts like credit card, personal loan and others . They also foray into aggressive investing.
When you have debts , the best strategy would be to clear the debts off before you start big bang investing. ( Of course, you can save and invest small portions to clear of the debt).
Another dangerous thing is investing in risky instruments like equity on borrowed money. This also can lead to grave consequences. It's always better to avoid such a thing unless you are highly adventurous!!.
