Reckless: (of a person or their actions) without thinking or caring about the consequences of an action.
It's typical of a youth who is reckless not to plan ahead. This is one of the most common problems among teenagers. They do first and think after, when it should be the opposite.
Let me be more specific, let's take as an example the youth who sleeps around, without caring much for what can happen to him/her each time they have sex. The result is as old as Adam: pregnancy! Only after finding out they're having a child together is when they begin to think of the consequences of that action. How foolish is that! Because of recklessness is that we have adolescents behind bars, in hospitals, addicted to drugs and many who are cold in their faith.
Think before you act. Don't fool yourself.
Food for thought: 'The wise watch their steps and avoid evil; fools are headstrong and reckless.' Prov 14:16
