Hello,
I'm not sure if I should say "don't lose focus of your goal" or "don't lose focus on your goal", or if both ways are grammatically correct? In other words, are both of the following sentences grammatically correct?
1. Don't lose focus of your goal, for if you do, you'll never achieve it.
2. Don't lose focus on your goal, for if you do, you'll never achieve it.
