2 Timothy 2:15

“Do your best to present yourself to God as one approved, a worker who does not need to be ashamed and who correctly handles the word of truth.”

Knowledge is something that you have to give some to get some. This means that with some people you have to learn things by giving knowledge to others and taking from them on their personal experiences. You will never know everything in life that you will need but there is always room to learn and that is why with knowledge you give some and you get some. Everyone is different on their knowledgeable basis. Learn what you can from yourself and others and share your knowledge as well.
