YES: we are brought up in an environment that encourages being careful about any decisions we might wish to make.
And yet again, every decision we do NOT take, or take too late, or with too little conviction, may just be a missed chance. Biologically, we may wish for things to stay the way they are because that makes us feel secure. But it also keeps us from exploring new - and maybe better - options when they present themselves to us... and act on them.
