Changing mind

Hello, I have to choose with two equal situations, I feel the same emotionally.  When I pick one, I have the belief and thoughts that it is the right decision and I should go for that one.  But the day after, I change my mind for the other one, because something comes up, insignificant and made me think that this one is better.
So I pick this situation, write down all my whys that I believe into (and I do) but again, change mind the day after.  I have solid arguments to choose both situations, both involve pretty much the same emotional suffering and great results that I believe for my career. I just can’t keep one and hesitating (it does not impact my work, I am still focus even though hesitating).  Any advice?  Thank you very much!
