I can't really work on more than one thing at a time
YOU CAN ONLY DO ONE THING AT A TIME SO CONCENTRATE ON IT.
I've realized that I can't multitask in the writing department; I can only kind of do one thing at a time.
Never do but one thing at a time, and never put off till to-morrow what you can do today.
I believe everything has a solution, and I take it one day at a time or one thing at a time.
I'm really so singular, I am only able to work on one thing at a time. I really am.
The real achiever do one thing at a time.
