This guy Dean Bokhari has really helped me out. And I mean
really helped me through crushing things like divorce. He's a former overweight Tobacco lobbyist who experienced what many adults have experienced, the 'what about my life is actually meaningful' question. Now he's this self-help guru/blogger who, having read over 700 self-help books, is like the Spark Notes of self-help.
So I am one to like things nice and neat, simplified, in lowest form (LCD) -- however you want to phrase it. I live by that quote Einstein may or may not have actually said, 'If you can't explain it simply, you don't understand it well enough'.
According to Bokhari, we have four basic areas that need to be tended: Physical, Mental, Emotional, and Spiritual (do what you want with this last one). If you're not getting exercise, socializing with family and friends, or paying attention to whatever your 'big picture' is, all on a daily basis, then you are essentially running on empty. His analogy is that those four areas are like buckets to be drained and filled, and if these buckets are neglected your whole life is off-balance. For example--and it may sound counterintuitive to some--exercise
creates physical energy.
As a pre-med, that mental bucket is constantly being depleted. Meditation, or any uninterrupted activity that requires focus, will refill that bucket (not studying!). I am not personally religious or spiritual, but I have found the simple exercise of meditation to be extremely helpful during stressful times allowing me to get back into study/whatever,
refreshed. Meditation = mind-vacation. Take them.
@Astra118,
check out one of his posts and see if it works for you; It's specifically about avoiding burnout by managing your time, those buckets, and avoiding Decision Fatigue. Additionally, if you're interested in meditation send me a PM and I can point you in the right direction.
