I used to get so much pressure in my old jjob. It was a very harsh, fast-paced environment. But I would just pray. I know that even if God does not take away the problem I'm facing, He will help me through it. And He always has. (1 Corinthians 10:13)
It's been a while since I had a high pressure job, but when I did, and things seemed to get stressful and overwhelming, I would look at what I needed to accomplish and I broke it down into baby steps and I just started working on it.. Baby-steppin' - until the job was done. The only way I could relieve the pressure was to get the job done that I needed to do and the only way to do that was to get started and move ahead.
