"鍵はスケジュールにあるものを優先するのではなく、優先事項をスケジュールすることです"

Simplified Meaning:

Imagine you have a to-do list with many tasks, like cleaning the house, meeting a friend, doing your homework, and watching TV. If you just try to fit them all in your day, you might end up doing the less important ones first, like watching TV, and run out of time for the more important ones, like doing your homework. Instead, think about what really matters most to you. If doing your homework is the most important, put that on your schedule first. This way, you make sure the important tasks get done before you spend time on the less important things. History has shown that successful people often make sure to focus on their main goals first, like when Martin Luther King Jr. worked tirelessly on civil rights because that was his top priority. By doing this in your own life, you'll be more likely to achieve what really matters to you.
