Not matter how attractive and lucrative a promise,it cannot outwit actuality in terms of reliability and credibility.
An average performance is far useful than an excellent plan or promise.
A single deed outweighs several promising plans.
It is better and safe to believe in a person or groups with average performance than to bang all your hopes in those with loud, clear and excellent but never to be fulfilled promises.
*Promise is one of the greatest deceptive tools, it is dangerous to believe, with undiluted conviction in a yet to be fulfilled promises.*
Do not be carried away by the attractions of the promises, you can be deceived and disappointed with nice but hollow promises.
Be careful and cautious with promises.
God bless you.
