Is it necessary to practice before preaching?

I think it is best if you do practice what you preach. Because it makes you look a little bit like a hypocrite if you are telling people how they should act/ do things if you yourself are acting the complete oppisite. I know alot of people don't and I myself am guilty as well. So while I think it's the best way to go about it. It generally isn't practiced.

It is very necessary that you practice what you preach. It would bring more credibility to what you are preaching in life. If you are not practicing it there is no purpose why you should sell your ideas to them. Where is the value of that if you yourself do not believe in it.

I think it's human nature that allows us to point at everything else but ourselves. We, and I mean including me, are guilty of preaching so much about how life or things should be when in fact we can't get our own personal affairs done as we preach should. Indeed it is necessary to practice before preaching. How could you know you're preaching is right if you yourself haven't done it yet? Nor got the experience to prove it does work? This is the main reason why my dad always says 'Never listen or take the advice on how to be rich and successful from a poor and unsuccessful person'. It's logical, how could he preach wealth and success if he doesn't have it? Right? Further, one book also gave me a good understanding about everything else, it's from the book entitled "The Richest Man in Babylon", one story there showed how the person who learned to save up (as it says 'fatten thy purse') lost his savings by asking a friend who was a stone builder who went to the village to buy precious stones for him. The moral of that story was not to entrust your money or gold on a person who's not in that field, meaning How can you let a stone builder buy precious stones when he's not well acquainted with them? It could be likened to those who practice medication (and dare advise others too) without properly studying the subject matter for years, it's like allowing yourself to someone's experiments. So there you go, when we do want advice, it should come from someone who's got the authority to advice. And who's better to do it but with someone who's got the experience, right?

I feel practicing what we preach is the best way of showing how sincere we are in what we have said.

If you do not know about a particular thing how could you on that.
