I agree with you, wholeheartedly! If you desire to grow in anything in life, you have to go the source with experience, relevant and factual information.

Sometimes the info is freely given, but sometimes not taken on board as much if it cost you nothing.

In other words, sometimes when info is free, it does not sink in as much as when you decided to put your hands in your pockets and pay for it! It shows you mean business!
