Invest in yourself by not just sticking to the traditional path of working 8 to 4 every day and studying hard. Take a step back, reflect on what you’ve learned, and don’t be afraid to try new things and explore different ways of achieving success.
Sure, it may have learned things required for the job, but it doesn’t do anything for a real-life scenario. At least nothing that’ll help you move forward in your career or make more money (as much as you might imagine).
