In accepting that suffering is a part of your daily existence, you could begin by examining the factors that normally give rise of feelings of discontent and mental unhappiness.
Although you may not always be able to avoid difficult situations,you can modify the extent to which you can suffer by how you choose to respond to the situation.
On Destiny: "Our destiny exercises its influence over us even when, as yet, we have not learned its nature: it is our future that lays down the law of our today."
