My attempt。 BW。 心靈篇。於我心有戚戚焉。題出得真棒！

無論境遇如何，我仍然選擇愉快的地生活，因為從經曆中我已得知大多歡愉與痛苦並不取決於客觀環境，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.
