I think someone who gives good advice is someone who is older who knows more about life and how to conquer the bad times. Anything that helps us ponder life in different ways and suggests ways to get through an inconvenience is always good advice to me.
A good advice I got, was from a social media video where a man talked about how we don't get every day for guarenteed. Every day, we take every day for granted and we don't seem to see the beauty of the world. Next time you're outside, breath in the air, act like today is your last day. You never know when it actually will be.
