A person who thinks that all they have to do is pay tithing to get into the temple is really, really mistaken. That is the easiest of the requirements.
Care to be specific about how easy it is to live the whole Gospel?
Several others requested an explanation, but perhaps she didn't see it. Here's a chance to expound.
As for myself, based on my own experience as a Mormon from birth, I don't think it was ever all that hard to 'live the gospel.' As I've said before, spending all that time in meetings and scripture reading was a bit boring, but not exactly difficult. Now, if you find yourself fighting the urge to indulge in habits you've picked up somewhere in life, such as smoking (or if you are resisting your sexual orientation), I can see how it might be hard. But otherwise, no, it's not that hard.
Obviously, if you consider not yet being perfect to be a failure to fully live the gospel, you could make it very hard on yourself. But I don't believe that describes most members, who are just trying to do their best, and don't beat themselves up for not being perfect.
