Whats in FUTURE?

Hello! I want to ask everyone one question. Each one of us once in our life must have compromised and sacrifised cause that is what is taught to us for a better life and future. By doing that is our future guranteed??? That by sacrifising and all our future will definately will get better.? Who knows whats there in future. But still we do compromise thinking somewhere its for good future. But what if its not? What if sacrificing for that thing is a waste? So what should be done? I am totally confused? What about you all?
