know what I want to do for the rest of my life

i’ve recently left a job of 17 years, a city of 20 years and friends for life to slow down my life a bit. my last job was all encompassing, a lifestyle so to speak. i am finding it difficult now to determine what is best for me, what i want, what i need. i used to make all my decisions on what was best for my job. now i don’t know how to make any decisions. i see two sides to everything. i need to find a way to get underneath my open mindedness and start figuring out ME. but how to start????
