Believe in the existence of God the superpower.
Generally, we will have some confidence in some people and we expect help or support from them. But when they behave differently we will have no say except maintaining silence.
That is why it is always better to have some alternatives so that our work will not get hampered even though somebody says no to the proposal also. Anywhere we should have plan 2 to use in case of plan 1 fails. Simply depending on the person and taking things for granted may not suit the present trend. Anything can happen and we should be prepared to face any type of situation. Your pain is known to you only and you have to manage accordingly.
So getting help is not our right. It is the prerogative of the person whi is at the other side capable of helping us.
Knowledge is power.
