(informal)when you say that’s the story of my life about a bad experience you have had, you mean you have had many similar experiences我就是这个命（表示多次遭遇类似的不幸）
Another missed opportunity—that’s the story of my life!又一个错失的机会——这就是我一生的故事！
Out of work with no money—that's the story of my life.失业在家而且身无分文 － 我就是这个命。
