All the knowledge in the world will amount to nothing if one does not have the guts to make use of them. Yes, it does require guts to use the knowledge that you have to either make a better life for yourself, helping others or to right the wrong. The people around you or those in power might be opposed to the use of that knowledge therefore you need to be willing to stand up and take action for what you believe is the right thing to do. You and your loved ones might be made fun of, criticised, threatened and even attacked. But there will be people who appreciates what you are doing. They will pray for you and be there for you. You might not see or hear them but know that you are not alone. On behalf of them, I thank you for your courage and strength.
