Valuing what you own rather than blaming what you lost

or

Remind yourself of what you have owned, but not miss what you have lost

別盡想失去的,試想你還擁有的
Will you still think of something owned instead of ever think of losing them.

別Don't
盡想think all about
失去的,what was lost.
試Try
想to think about
你還what you still
擁有的have.

別盡想失去的,試想你還擁有的
Don't want to lose, just imagine you have

Don't want to lose, just imagine you have.

Don't dwell on what has been lost, try to think of what you still have.

以上是直譯你的句子

假如按意思用較簡潔的英語可以創作為鼓勵的語句：

Look pass your losts, Cherish that you possess.

別盡想失去的,試想你還擁有的
"Think what you still have and not what you have lost."

lost past participle, =to have something taken away from you.
evaluate v , =form an opion of the value or quality of something after thinking about it= assess to your GF ,your gold wrist-watch etc as shown in TVB.
Hence:-Rather than blaming what you lost , just evaluate what you own.
