It is better to study everything before you make the final decision. However, too much delay will not be the best. Before you say jack, a smart one elsewhere will snatch your dream choice due to delay.
In football, strikers who over-delay mostly miss the spot kicks. The situation is the same everywhere. When you are interested in anything, don’t delay after you have taken your decision.
Never share the intended person you are about to marry with a friend who is also single, women mostly suffer from such information. Many married wives lost their husbands because they share every bit of their information with their friends. It is bad practice, your privacy is your power, and people who fail to shut their mouths mostly end them into trouble.
Take this caution seriously, delays are dangerous!
