If you make a mistake and are too embarrassed to correct it, then you're making a second mistake. Don't make any decision you're not qualified to make. Go to others who know more. Respect their advice. Don't play games with your life.
Living means growing.
If you don't make decisions, you won't grow. The more informed you are, the better your decisions will be. Evaluate fairly, not based on prejudices. Be a judge, not a lawyer. Whenever confronted by a decision, relax.
