Hi sparrow bird,
I have actually been going through Jupiter return for the second time ( the first time was when I was 12, well I couldnt really remember anything special happened then , although my study started to be so much better at the age of 12 on wards , probably because during the transit , it made aspect to uranus in the 3rd )
Anyway, I am not particularly sure about meeting new people, like Solar said , it depends on which house Jupiter resides in an individual chart , one might attract many friends when Jupiter crosses over their 11th and to the lesser extent the 7th house , or when jupiter makes a connection to a planet that is in the 11th house. My jupiter is in the 5th which is supposedly a very good position for the jovial planet to be in. And I have always been able to express myself without much problems. However , as my Jupiter is in retrograde motion , much of the joys I have were acquired my own ability to make them happen, rather than having the joys brought to me by external factors. Also , I have not seen the promises that Jupiter returns seems to bring, except that it does seem to make me mentally restless ( sextile Uranus and opposition Mercury ) . In fact, Jupiter has not done anything to me this year , it has on the contrary left me a huge pile of irresponsible horse cr@ps to deal with. I am hoping when Jupiter goes retro-grade , I could see some promises and benefits come true.
Harsh Jupiter usually brings a lot of faith and optimissm into one's life , also much recklessness , too much carefree , a tendency to overlook finer details.
I wouldnt rely on Jupiter too much though, it seems to always promise more they It can actually give. For that , a transit saturn has been more my favourite. At least with hard work, I know transit saturn will always give me a rewards afterwards.
