Now I'm going to make an assumption that you aren't neglecting more than one part of yourself (but it you are, work on it!). If you are physically and emotionally taken care of but not mentally sharp (1), you may start to feel like you aren't being challenged and that you aren't learning anymore. Try to play a game (that requires some reasoning skills), research a topic that interests you, read a book, learn something new. It's very important to always being learning something new, even if you are no longer a student. If you are emotionally and mentally happy but not taken care of physically (2), you may notice that you get tired often and that you may be gaining some weight. It's also possible for you to have more anxiety or depression if you don't regularly exercise. Luckily this one is easy to fix- go for a run, make sure you have 8 hours of sleep at night, shop the outer ring of your grocery store and pick up fruits, vegetables, dairy, and whole grains. This is an easy trap to fall into if you work crazy hours and don't have a lot of time. However, it's important to make the time to treat your body right, since you will definitely begin feeling healthier, more alert, and productive throughout the day. Now let's look at 3, where I was stuck for a while. You make the time to eat right, exercise, and continually stimulate your mind. However, there is just a part of you that feels unsatisfied. This is because you don't make enough time to develop the emotional part of you. It is important to see your friends and family, indulge in a hobby or pleasure, have a really good laugh every day. By prioritizing this time, you will begin to feel yourself have a more positive outlook on everything. Don't see reading a book as a waste of time, but as an act of enjoying yourself and building that emotional part. Finally, if you are nurturing all of these parts of yourself (4) you should probably be giving me advice!
While all of this is interesting to know how these parts of a person develop, a key takeaway for me when learning this was how important it is to commit time to each one of the 3 components. I would always set time to hit the gym and challenge myself mentally through research and games, but I never set time to take care of the emotional part of myself. All three parts really need to be prioritized; I'm not saying you have to only eat carrots, work out every day, and dance around your office every minute. But it is important to address all three of these components at least every week.You will really feel the difference!
