When someone asks for your advice on something it’s important to understand that just because you give them advice doesn’t mean they are going to (or should) take your advice. Sometimes they have asked many others for their advice as well. Other times they have thought about your response and simply chosen to go in a different direction.
Just because you give someone advice does NOT mean they are obligated to use your advice. It would be nice for them to thank you but anything else is purely optional.
If you find that people are regularly ignoring your advice, the problem might not be with them…you might want to reconsider your advice.
Have a great day!
