I've had my fair share of bad cooking days and it can upset me for weeks, super-analysing every step of where I went wrong. I've also had my culinary highs and it makes me so narcissistic. It's as if I can handle any problems that life throws my way when I can whip up something that I didn't think possible.
God wants us to savor life even with its ups and downs. He says He has overcome them. And I believe Him. No analysis, just a simple faith. Just believe.
