Advice for starting a new Gemara study

Hi Mickey.
I am a graduate of a reputable yeshiva and studied two Gemara courses (study and proficiency) for two years in the yeshiva, and during the rest of the time I studied a lot of thought and especially philosophy, with an emphasis on your books, which for me completely changed my life.
Since I left the yeshiva (about 5 years have passed since then) I have not studied Gemara at all in an organized manner and certainly not with the proper attention. I recently bought the Responsa Project with the intention of returning to study Gemara at least once a week and I am now trying to find the ideal Gemara for myself to review and start anew with in-depth study. I want to say that I am currently looking for more Gemaras with a lot of intellectual issues and fewer complicated and financial issues (the bull that went after the cow, etc.). I would love to receive advice on an interesting Gemara that I should start with and perhaps in general how you would recommend that I return to studying? To study the Gemara on my own or at least start with some kind of guidance, such as your pages on the issues you have taught and published on the site.

Thanks for the help.
