My suggestion to you, whoever you are, is to dedicate 1 day to something that’s important to you.
A few examples:
If you are planning to apply (or have already started to apply) to graduate school, spend a day working on your application, cover letter, personal statement, and interview skills.
If you want to give back to the community, spend a day volunteering with a nonprofit.
If you want to find out more information about a specific topic, spend a day researching it.
In other words, if there is something you’ve been putting off or avoiding that you need (or want) to do, make the time to set aside a day and focus on it. You might be surprised what you can accomplish.
