Christians are often accused of seeking God for their own comfort. I think the opposite may be true in that non believers choose not to seek God because they do not wish to have their lifestyle changed by the demands of religious faith.
I can see them choosing a particular sect based on what they're comfortable with - psychologically and emotionally - but whether or not you believe isn't something that you choose. I don't know of anyone whose reason for not believing is 'well, it's such a burden'.
More to the point, the lifestyles that we develop as we grow are, in part, a result of the nature of our beliefs rather than predominantly the other way round.
Christianity is not a comfortable religion. To be a Christian involves taking up your cross and following Christ. And emulating the words Christ spoke to the Father: "Not my will, but thine be done." Jesus warns us that as His followers we will be called to follow paths we would not wish to take.
That's your take on Christianity. There seem to be a considerable number for whom Christianity means acknowledging the existence of a deity and just generally trying to be a nice person: that doesn't really sound very different from my life of not acknowledging the existence of a deity and just generally trying to be a nice person.
So why should we choose to seek such a challenge? In doing so you will find the ultimate joy of fulfilment in achieving what God brought us into existence for.
You hope... you might be right, of course, but you might not.
