I’m Easy To Give Yet Few Will Take

I have a monopoly on the young,
And at times, it’s true, I may have stung.

What am I?

Advice. It’s easy to give it out but advice is often ignored. Brides are frequently given advice on their wedding day and you’ll even hear life advice at a funeral. Advice is frequently given to young people and some advice can be hard to stomach (like you should lose a few pounds).
