Wisdom is gained by experience and understanding. I have been told, "I am wiser, because I am older and have more experience." Hmmm...yes and no.
More experiences simply by living life for a longer time is definitely a possibility. That is not the same as wisdom. Without the effort of nurturing an understanding of those experiences on a spiritual level from your soul's perspective it has most likely created fear. Nothing about fear is wise.
Fear is a primal, neurological response. Fear is not a soul response. Fear is a learned response. If fear was natural we would still be scooting around on our bellies like babies, because we would be too afraid to stand and run lest we might trip and fall.
Use your understanding to be more compassionate to everyone you meet. Remember, being helpful doesn't mean you "should" on people like the opening comment does. It doesn't mean you shoot off your understanding and advice like spitballs. Nobody appreciates being spitballed. Show people respect by asking them if they want your help first. Help by listening, being present with them wherever and however they are and acting as God's hands of love. It is already within you. Use it!
