Retrogression is a kind of a strength of a Planet ...where planet will not let go things easily and try even after repeatative failures.so if in Sagittarius ascendant lagnesh has gone to 3rd house of courage and retrograde means native will not accept defeat easily and keep on trying again and again. It's difficult to convince such a native as they are over confident. But where retrograde planet sits.. instability comes in that house.
@Ruchi Bhatia like 3rd house is for short trips, inclination/skills, siblings etc.. like not able to plan short trips in one go. Not sure about your inclination
