Apart from your fellow gym buddies, you work completely different shifts to everyone else that you know in your life. Weekends and evenings off are simply not going to happen and there are times when you can go from working late the night before to picking up the morning shift the day after. There isn't a lot of room for having a pumped up social life, mostly you'll just want to nap or squat instead of heading on a night out. But the important thing is is that you love your job and after all, you're changing someone's life. If you have anything to add, feel free to comment in the thread below.
