My life - as every other individual's - has been ful of crests & troughs. A crest or a trough can be defined as an instantaneous value (or a relative value based on the situation) in mind when, whatever one says is considered right & acts admired or is considered worng or criticised; respectively.
On (Mathematical) integration of this value (of a crest or a trough) with limits from 0 (the date of birth) till today one can identify the absolute value of the highs & lows. This is how success or failure is defined.

Based on the above this is the crest of my life. But surprisingly, on integration the result is neither a success nor a failure!!!
Probably because the crest is a relative term (as mentioned above) & I can still sense there is a lot to achieve (The birth of self motivation).
