Learning to trust

So hard to let go sometimes *sigh* especially when it comes to something that you've got. Grrr ... all these insecurities associated with living in this world today. What im trying to let go willingly is this job that's been offered to me by Royal North Shore hospital in the food services / nutrition department, which would be such a great experience! I mean, in wanting to become a dietetian at that hospital, what better experience now as an undergrad? But it's a 7-day rotating arrangement, which means that it's 7 days on, then 2 weeks off, then 3 weeks with 7 days a week on, then another 2 weeks off, which repeats. And it's 5-9pm, something my mum is totally unhappy with. But yeah it's wise to let go of this opportunity i know. Need to learn to trust God more and lean not on my own understanding, because He knows what's the best and He alone will provide!
