What an excellent question! You are already showing wisdom by asking it.
First, it's important to clarify your ethical values and determine how you will respond when others try to compromise them. Remember, not everyone may be as wise or intelligent as you are.
Next, educate yourself about safe sex when you are ready. Many people mistakenly believe that sex is only intercourse, but that's not true. Understand that all sexually transmitted diseases and HIV are transmitted through bodily fluids. Contracting any of these can have a lifelong negative impact on your life.
If you are a guy, seek advice from someone you respect on how to treat women with respect. Learn that "no" means "no."
If you are a girl, have a conversation with a woman you look up to about how to identify trustworthy guys and demand respect.
Now, on a lighter note, it's important to take your future seriously. Avoid engaging in activities that can lead to a criminal record or hinder your chances of getting the right job. Make smart decisions now to achieve what you desire later in life.
You may have come across stories of college hazing, so I want to emphasize that you should never stay silent when witnessing any form of abuse.
Imagine your life as a series of stepping stones leading you to your adulthood. Make each step count. Stay curious and take your time in making decisions. But when you do make a decision, ensure it brings you closer to the life you envision for yourself.
Above all, have a great time! Life is full of wonders and joy, and you can attain whatever you desire if you make wise choices as you navigate adulthood.
I genuinely appreciate your question. Perhaps it's because I grew up in an empty room without parents that I wish I had such wise guidelines when I was growing up. You are already wise, as evidenced by your question. The world needs more individuals like you, so make us and yourself proud.
