I want to share my problem as I can't help it. I have a growing business as I'm really enthusiastic about it. But the real problem is that I have to speak lies to make it grow,
But the real thing is as soon it is done a feeling of guilt appears instantly
Also in some cases I really don't want to speak lie but I can't help it.
If you have something to help me out, please make it.

You have only two choices:

1. Get honest and find constructive means of employment.

2. Lie until your business folds (and it will) sticking you with a huge pile of guilt and now regret too-- causing you to spend all your hard earned cash on distractions like booze and such to avoid looking at what a trainwreck you've created until you are more broke than when you first started. If you don't want to believe me, duck into any open AA meeting to hear your (future) story being told! LOL

You think your problem is you "need" to lie when your real problem is that you lie at all, including to yourself!
Its called d-e-n-i-a-l... (Don't Even Notice I Am Lying)

No, you do not ever have to lie to make your business grow, you may not tell someone everything, but you never lie in business to have a successful business.

Con men lie, good businessmen learn not to say things or change the subject

As noted you believe you have to lie, you don't, you need to just learn proper methods in what you are doing.

Why do you think you lie?

Honesty brings "prosperity" in everything you do.

I have to spread some reputation around before giving you some again, Teaching but WOW, you could not have said a more important thing here than if you used the loudest possible bull horn from atop the tallest building in the world (Sorry, I've lost track which one is! LOL).

Thank you for the kind words. I have seen it over and over again in my life, it should be our reminder of our actions.

Positive thinking brings positive results.
Lying is negative thinking and negative thinking brings negative results.

I agree with Fr_Chuck, just don't tell them everything. Polish up the good points and play down the bad points. - And stop beating yourself up.

Big advertising companies can't afford to lie because they are afraid of law suits. But they sure know how to manipulate the market. They also use 'tricks', like using psychologists in order to discover what colour to make a package that will make it appealing to us consumers.
