i (don't) know

i don't know how tomorrow's gonna go. i don't know where i'll be stealing time to eat lunch. and if i'll have to fly to eng'g right after my first class. i don't know if i'll get to study for all three subjects and for tomorrow's meeting with the clients tonight since i just got home. i don't know if i'll have enough energy for my night class. i don't have everything planned. but i know He will sustain me.
