To miss opportunities

The worst thing is to be frightened, isn't it?

When starting a relation one can not be too afraid to be hurt.

When arranging a party one can not expect it to be too boring.

When giving birth one can not be too afraid of the pain.

When living one can not be too afraid of death.

When applying for a job, one can not fear not being able to manage it.

When making a jump one can not hesitate at all.

To be afraid is to miss opportunities in life.

To miss opportunities is a shame, isn't it?
