As a Junior Software Engineer you have a long career ahead. It can be tempting to work all hours proving yourself. I promise, you will have plenty of time to finish that pull request, method or unit test. Maybe 40 years or so. Start creating work/life boundaries right now, it will be much harder to do so later in your career. Block out exercise time, make your lunch break sacred, delete Slack from your phone. *-Mani Bhushan*
