Define hesitation. At some point in my life I went through all sorts of mental gymnastics to make free will work, probably to stave off some sort of existential dread. But that was a long time ago. And the mental gymnastics didn't make sense. It's impossible to make free will work on any level. Once I accepted that, there were no more mental gymnastics, no more struggle to make anything work, because everything made perfect sense. The only problem were the implications, but life is what it is, and nothing can be done about it.
As for accepting it in daily life, it doesn't really work like that. Most of us, me included, live our lives in the delusion that there is free will. I can deduce it rationally, but ironically my body won't let me truly accept it, because it goes against everything billions of years of evolution have been striving towards. Life needs things to matter, especially one's own actions and decisions, even though it is all a lie. At best, I can force myself to see certain situations from that point of view for short amounts of time, or keep that idea at the back of my head, but I never really had any choice in the matter either.
The only other option would be a sort of enlightenment where one accepts everything, especially one's own death and suffering, with absolute detachment, without horror, blame, or the desire for something better. There might have been people throughout history who approached that state of being, but it's hard to tell, and it's not something a person can actually make themselves into. If it happens, it just happens.
