the most important thing

i was thinking this morning...maybe stressing is a better word (though i'm trying really hard not to). there are several things that are up in the air right now...things that i don't know how to move forward on, or if i should move forward at all. for example:
where should i go to church?
where should i get a job?
what kind of job do i even want to get?
should i go to seminary?
should i write that book i've been thinking about?
just to name a few.
so as i was thinking i felt compelled to meditate on John 15:16 "you did not choose me, but i chose you and have appointed you to go and bear fruit-fruit that will last. then the Father will give you whatever you ask for in my name." and i reasoned with myself, "ok, i didn't choose this walk with God. HE chose me. He's got a plan" (i keep telling myself that last part). and then i thought, "so what's the most important thing?" well, it's to "love the Lord your God with all your heart and all your soul and all your mind." duh.
when they asked Jesus what was the most important commandment, He didn't say, "be holy" (though that is really important). He also didn't say, "find out the will of God and do it." Neither did He say, "please God." i think that all of those things fit under loving God, but they are not the main idea. LOVE GOD.
what the heck does that mean? i know what it means, but when that's supposed to be priority #1, what does that look like in my daily life?
i think i know the answer, but i feel like it should be something phenomenal.
is it really that simple?
