One thing I have noticed with people my age, from about 15+, tend to waste away their lives, power, abilities, kindness, etc. for partying, drugs, alcohol, promiscuous behavior, etc. Sure, partying, flirting, promiscuity, smoking and drinking are fun now, but what will happen later?
Maybe your promiscuous behavior in high school will carry on into college. For example, a girl or boy is known for being a flirtatious, pretty/handsome, immature individual who will probably jump on any guy/girl who looks decent and smells nice while in high school.
Once he or she goes off to college, sure, some old high school classmates may be there too who know of his/her history. They tell their new friends about your past; the new friends tell their friends about this individual and rumors of STDs start, and before you know it, half the school knows how much of a low person you ARE.
Notice I use the word "are" because although this boy or girl may have wanted to change once in college, the past actions still follow, and people will still think he/she is that way. Now, new college people may look lowly of this individual, not take them seriously when trying to get to know someone, or might even take this past promiscuity knowledge to their advantage.
Then, the past can carry on to a job. People always take pictures, and although you can "un-tag" yourself, that person STILL has the blackmail, even if it's you in the background of a picture holding a beer can. No job wants a drug taking, flirtatious bum around.
Then, the stories of promiscuity can be told to you wife or husband. And how shocking would that be to find out your wife or husband was a high school hooker/tramp/words-you-can-probably-fill-in-yourself.
It kind of makes me sad to see people who have the potential to be great, but they waste away their intelligence and talents for useless actions that will mean nothing in the future. I'm not saying to stop partying and having fun. Just do it in moderation. Not EVERY weekend.
And picking up on bad habits now will bite you in the behind later, like smoking. Just look at the health risks & not to mention the money...
The average box of cigarettes costs $4.50. If a person smokes 2 and a half packs a week (this is being modest), that is $11.25 a week, $45 a month, $270 in 6 months, $540 a year. That's $5400 wasted in 10 years. Not to mention the chances of lung cancer, mouth cancer, heart attack, high blood pressure, cataracts, premature aging, yellow teeth/nails, chronic bronchitis, and emphysema. (There's alot more, but I'm not typing it all) Not to mention low birth weight, premature birth and a possible cause for SIDS in infants to mother who smoked while pregnant or smoked after their birth.
Besides, who wants to look like this when they turn 40?!
I would get into the effects of alcohol & possibilities of STDs, but I'll save that for later. =D
Just words of advice, think twice about your actions and see if you can do something worth while, like volunteering, letting that car over that has on his signal, or giving someone a flower you picked instead of grinding on some guy, girl hopping and drinking your youth away.
