The Meaning of...Meaning

The dictionary definition of meaning is the significance of something. I think that meaning is the answers you get for all the things you question. When you seek meaning, you're seeking to understand something that is unintelligible to you. This is why you hear (and read, and see on tv) about a lot of people searching for the meaning of life. They're not sure about their significance and purpose for living.
I think this is the definition of meaning because you never hear someone ask for an explanation about something they already know (an example would be a math teacher asking for someone to explain algebra to them). Another reason I believe this is the meaning of meaning is because in media (commercials, adds, ect.) there is always a message advertising companies want to get across to consumers. Most of the time the message is something along the lines of 'buy this product' or 'your life will be so much better if you get this'.
