All is well that ends well
No work or performance can be judged properly by what it looks like at the beginning or in the middle because what looks well or promising at the primary stage may turn out to be unsatisfactory in the end. It is equally impossible to know how a chain of events will conclude. Certain events occur well in the initial period but lead ultimately to a disaster. So a thing or event can be known for what it actually is when the end comes. The result is a really important factor, and a thing can be claimed to be good or bad only after proper consideration of its results. Thus, it is only how things end that determines their value.
