Short-term performance may get noticed; however, achieving success takes time and years of sustainable performance are far more important than short-term results. 

Traders and investing markets work according to cycles; hence, even good approaches have periods with significant drawdowns. As a result, those who work towards survival continue to pass through positive market conditions as they are still in business and functioning because they concentrate on preservation. 

Therefore, longevity denotes professionalism and maturity.
