For me it really depends what areas we speak of. I can say that, generally, it tends to be easier for me at this point of my life not to get what I want. I think because in my youth I did not have many rejections and I pretty aggressively pursued anything I wanted, often excessively (think of obsessive and addictive patterns). Life of course brought many experiences where things did not go the way I wanted, I experienced some serious challenges and adversaries, I actually destroyed a few things that I wanted or almost... So lots of adult conditioning. But there are still areas where it is easier to face and process rejections and not getting my way - for example in the interpersonal world. That has never been too challenging for me. I still have hard time not getting my way with my work, for example when I have interesting project ideas in mind but can't find the resources for it or when the product is not appreciated as much as I would like. Rejections and not finding exactly what I want in personal life is much easier for me, perhaps because I do not self-identify with those things as much and I don't get attached to those things as much as I do to ideas and projects.
