fear of g-d vs love of g-d

if the reason you follow the torah is due to fear of g-d , well that grows old fast, especially when one's alleged fear of g-d is often really fear of peer pressure. i think that after awhile a person has to observe the mitzvos because of their love of g-d which a lot of the time is really their love of doing the mitzvos. 

of course in the end it really has to be a mixture of the two philosophies. if you only do mitzvos because you love g-d , then you may figure you don't have to do so much because heck he will forgive you , he loves you and he will understand. you need a little fear of h-shem so you actually stay observant.
