Courage
Courage is not the absence of fear,
but having it and persevering anyway..

Confidence

Does fear keep me from persevering?

Come out of doubt into certitude...

And if he feareth not God,

God will make him to fear all things;

whereas all things fear him

who feareth God.

What support may i need to boost my confidence / courage?

Though the concept of the "fear of God" is not palatable to many, there are also many cultures that often describe a virtuous person expressly by emphasizing them as a "God fearing person." Also, among many people who have battled with substance abuse, a fear of consequences is equally considered "a healthy fear of God." Thus, although the concept may not feel useful for some people it still, nevertheless, proves  very useful to others.
