Do i wanna leave?

That question has been bugging me for the last 2 months. Do i wanna leave the company? And i still don't have the fucking ansewr. I applied for the internal opening and i'm really hoping that i get it. I really really want that position. But the BCB ppl finally called me and they want me to start 1st July. Which means if i take this job i would have to pay the comapny back at least a month. A few other ppl have said it would be better to move on to better things. And sometimes i think that's right. But other times, i'm just so happy there. I'm alrite with the job. I know my job well. Ppl respect me and look up to me. My managers are alrite with me. I've got great friends. And i'm thinking, if i'm so happy, why leave? Isn't personal satisfaction more important than anything? But someitmes i feel so restless. LIke i can be doing so much more with my life.I can be doing somethign so much more challenging. Sigh.. i really dont know. I feel like i've hit a rock in my life right now. Whether to still cling onto that rock or let go and let the current sweep me away to other places. I realise that i've got several of these type of posts before... but like i said... the question of moving on has always been there but i just don't how to answer it.
