He that refuseth instruction despiseth his own soul: but he that heareth reproof getteth understanding. Proverbs 15:32 KJV
When you quit learning you quit living. Everything learned brings a freshness to life and can open the door to your future.
There is never a time, no matter how old you are, that you cannot learn something new.
You may not like the messenger but everyone has something in them that you can learn from.
Listen, pay attention, to each person you meet. They all have a unique story and perspective that can only be gleaned by the attentive.
Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. Philippians 2:3 KJV
For there is no respect of persons with God. Romans 2:11 KJV
