"Yogastha kuru karma tvam sangam tyaktva dhananjaya|

Sidhyasidhyoh samo bhutva samatvam yoga uchyate||"BG2.48

"(Therefore) You should perform focused only on acting with good intentions, completely detached from expectations. Thus shall you have equipoise towards (short term) successes and failures. It is this equipoise that is the essence of Yoga"

"Karmanyevaadhikarste maa phaleshu kadachana|

Ma karma phalahetur bhu ma te sango'stvakarmani|| BG2.47"

"It is your duty only to act with the Right intentions, for actions alone do you control to influence outcome. ("Right" here is that which in your honest estimation and that of the collective wisdom of the past (shruti/smriti/itihaasa/Purana) is good for the well being of yourself and others). Outcomes are never in your complete control nor will you ever have a good judgment of which outcomes are beneficial to you in the long run. Therefore do not let your actions be dictated by perceived short term benefits to you nor should you let consequences deter you from doing the right thing"
