Everyone has experienced a negative person at some point in their lives. Some people don't mean to be negative in their attitude, they just can't seem to help themselves. Other people come across as having a negative outlook because of something they've experienced. Perhaps they're lonely, or insecure, or even scared.
If you're a parent your child at some point was afraid of not having any friends, being bullied at school, or worried about missing you when you went out to dinner and left them with a babysitter for the first time. They might have been afraid and tearful the first time you left them at the doorway to preschool or sent them to camp. They may have been overwhelmed their first year of college staying in the dorm and having to do their laundry on their own. Our children grow up and will undoubtedly learn from their experiences and mature along the way. They will have their moments of feeling like they can't do it without you, but they will. They'll surprise you and they'll surprise themselves. They'll learn to notice the positive things in life. They'll learn to discard the negatives that can pull them back.
Then there are the people who can have you reaching into your cupboard for the biggest bottle of Tylenol you can find to try and curb your mounting headache. Some people (no age requirement) can be just plain cranky. Some can be exhausting. You have to dig extra deep at times to try to turn their negatives into positives, but it's worth it to keep trying. Don't let them rain on your parade or dim your light. Show them (over and over if needed) that there are positives in every situation. Sometimes, depending where a person is at, it's hard for them to find a bright spot. Help them find it; point it out. Doesn't matter if it's big or small; they all count.
With perseverance and a strong will you can help others find their positives. Your light will shine a little brighter and they'll start to notice. Your positive attitude might even rub off. Consider it a life experiment.
