"天天向上" (tiān tiān xiàng shàng) is a Chinese phrase that translates to "improving every day" or "striving for progress daily." It's often used in a positive context, encouraging continuous self-improvement and development.

So if you're asking whether one should strive for daily improvement, the answer would generally be "yes" from a motivational or aspirational standpoint. However, without more context about how you intend to use this phrase or concept, it's difficult to give a definitive yes or no response. Is there a specific situation or question you had in mind?
