Scientific Outlook on Development Youth Slogan

The first half of your sentence "Scientific development dominates the overall situation" is incomplete, but it should be "Scientific Outlook on Development dominates the overall situation". But I don't think the first half and the second half of this sentence are easy to say.

I suggest: Take Scientific Outlook on Development as the guide to comprehensively improve the work level of the Communist Youth League! Or: Stick to Scientific Outlook on Development and raise the work of the Communist Youth League in our city (county, school) to a new level!
