My attempt。 BW。 心灵篇。于我心有戚戚焉。题出得真棒！

无论境遇如何，我仍然选择愉快的地生活，因为从经历中我已得知大多欢愉与痛苦并不取决于客观环境，境由心生。

No matter what the circumstances are, I choose to make a life happily as always, because as per my experience I know that most of delights and pains are not up to objective enviroments, but up to what you think.
