You can end suffering by not craving the items of suffering but instead refuse, if you do, you will achieve nirvana, the freedom of desire and craving.
The end of suffering is the eight fold path, which is developing understanding, positive intentions, skillful speech, action, lively hood, right kind of effort, cultivating mindfulness, and mastering Meditation.
