You don't need to force yourself to sleep 8 hours... the ideal situation is: You close your eyes. You open your eyes. It is now (about) 8 hours later.
If this is not how your sleep happens every night, then likely there is a problem somewhere in your body. Which
might be fixable.
I insist on this point because I was among the people who would say 6 hours are enough. I would wake up every day after 3-6 hours of sleep and feel noticably more energetic than everyone else so I thought 3-6 hours are enough for me. Must have been some sort of super power aye? And then I graduated university and did some other changes to my lifestyle and suddenly I was travelling in time 8 hours every night. Best feeling ever. Now, I am back to having lots of dreams and often getting woken up by them. I am working on the problem and trying different solutions, eventually I will get back that best feeling ever of time travelling 8 hours a night. My point is - you can have better than what you currently have. You say you CBA doing workouts and stuff - is that because you feel tired? Or is there another reason? Because ultimately, you need some form of exercise in your life. And by the time it starts showing, it will be too late to fix - when you get to 40-50+ years and everything suddenly hurts, you get sick every month or worse - you get some life threatening shit like heart attack or insult and so on. You are just a human, like all of us. You might think you don't need it, but your human body does. And if the main reason is not having the energy for it - well, perhaps sleeping only 6 hours is not good for you after all :P And if the problem is time... well if you have time for raiding and games in general then you can't really use that excuse.
If raiding is an activity you
genuinely enjoy then yes, I do agree. My problem with people is that they force themselves through things they don't necessarily enjoy in order to achieve some goal which they themselves don't know why they want to achieve. I understand it's not my place to tell people how to live their lives. But... there's so much more to life, you know. In your case, you do seem to be more content with your life than other posters here so I won't pry any further. A genuinely happy life is the most important thing, in my opinion. I am strict when it comes to my own health and productivity, because I want to die happy, fullfilled without pain and without regrets.
I am 24 btw and my fiancee is 23. Been a full-time night shift worker for 1 year now. 1 year ago I had to make my choice: Do I become a Mythic raider or do I quit raiding altogether and focus on things I enjoy. My job has a crazy low workload - sometimes I finish work in 15 minutes, more often in about 1 hour (out of a 9 hour shift) and I work from home so I can basically play games all I want. I did have the time for Mythic. I was close to having the skills and gear so I could get there if I put more effort into it. I just made the choice that I don't want to spend so much time every day on something I don't necessarily enjoy. I love getting more powerful but I don't need to be THE most powerful. And right after I made that choice I realized that I couldn't raid anymore anyway because most guilds raid during my sleep times and my realm was an Alliance RP server so close to zero chance to find a morning-noon raiding guild. Ever since then a huge burden was liften off of me and I've been enjoying a wider variety of games and hobbies than ever before. And now I am enjoying doing Torghast on multiple alts. I can entirely skip the gearing process on my 11 alts, because I can do lower Layers on them and only do Twisting Corridors and weekly Layer 8 on my main. And I can do all that whilst staying true to my ideal lifestyle.
I will be graduating from this thread as people tend to deny anything they don't understand and if I keep falling into their trigger traps it will only hurt my sanity more
