Somehow, I tend to interpret that as "five years from now." Don't worry about what you're going to do after grad school. Just worry about the next four years and I'll take it from there.
Sure, that's true. But if I interpret it that way, that still leaves a whole lot of stuff that I have to deal with myself. That still leaves me days like today, where I literally worried myself physically sick about whether I'm "meant" to stay in my clinical program or grab this research idea that's rattling around in my head and leap off into a Ph.D. program instead.
I need to remember - He really meant tomorrow. Do not worry about January 14, 2016. Only worry about January 13. Period.
Don't worry about your gigantic remediation meeting next week. Today's worries are sufficient.
Don't worry about which program you're supposed to be in. Today's worries are sufficient.
Don't worry about whether that nice guy will ask you to lunch with him tomorrow. Today's worries are sufficient.
Don't worry about your first day back to clinic after a long vacation. Today you can practice; you can't do the clinic visit today, so only worry about the practicing. Today's worries are sufficient.
Don't worry about organizing an on-site visit to give a speech about hearing conservation in two months. Today's worries are sufficient.
Don't worry about finding an externship and moving away from home for the first time. Today's worries are sufficient.
I can't reach into the future and manipulate any of these things today. I can prepare for the meeting, carefully research all of my options with the two programs, pray for God's leading on the nice guy, practice my clinic procedures, read over the speech assignment, and begin praying about my externship. That's the stuff I can worry about. But as for the actual meeting and the actual guy and the actual clinic day and the actual speech and the actual externship, those are all "tomorrow" problems and they are all in God's hands, not mine. Therefore, worrying about them is not allowed, and only results in dreary wandering through a dreary day with a churning stomach and the shudders.
God is Master of all of Time, present and actively working in every second of all existence simultaneously; but He has very kindly divided this unfathomable thing into linear, bite-sized chunks we call days. One day is more than enough for me to handle - if I want to learn about faith and avoid stomach ulcers, I need to learn to let Him handle the things in the future, and just to focus on the tasks He set right in front of me. Today. Not tomorrow. Today.
Sufficient unto the day is the evil thereof.
