Get to know people, understand them before you trust them with your heart. You never trust in a hurry, you should always verify and confirm.

We live in a world which is so artificial; people are making their own rules and choices, a world where wrong is right, abnormal is normal, a world where real is rare. A world where Lemon flavour is used for a "Welcome Drink" whilst the real Lemon is used in a "Finger Washing Bowl".
You can be real and good yet used by people. So make sure you are with the right kind of person. Don't remain in any bad relationship because you think leaving will be a waste of time. One thing you might not understand is that, yes the relationship didn't bring you what you wanted but at least, it taught you what you do not want. You are worthy; don't let anyone reduce your worth to a piece of cigarette in the name of love.
In conclusion "So be careful how you live. Live as men who are wise and not foolish. 16 Make the best use of your time. These are sinful days"
