Do you think that all those are required in order to be in check? I noticed that what you mentioned is a very common formula among my colleagues - gym almost every day, bland @ss chicken breasts as "meals", waking up early and sleeping early, etc. It just seems so structured and boring... no offense. I'm not sure why sitting around and eating processed food would make you miserable, or the lack of gym or structured life. Only ones that make sense is getting enough sleep, having enough money, and doing things you enjoy, even if that means fatassing all the time. That term was introduced to me by my friend.
I gave up on dieting and exercising. I don't seem to gain or lose weight with "proper diet"/exercising. I'll probably die early since I don't gym, sleep like a college student (sleeping at 3 or 4am lately as I post this at 325am lol) and eat one massive meal at the end of the workday... but I'll contend that I'm happy. Hopefully, I'll be like that guy who smokes a pack a day for 40 years and lives to be 100+. Perhaps we are in different stages in life, but what you described just feels like something older people do.
In your checklist of happiness, I would say that quality sleep is the most important. Sleep is like the reset switch of the body and mind. If you are able to sleep and be physically and mentally refreshed regardless of the day's problems and exhaustion, then that's all you really need + money. How you achieve this kind of sleep, I wouldn't have an answer for that. I can generalize the personalities of those that are light sleepers, but it would merely be conjecture and probably offend the hell out of people.
Good question, and I guess I will sorta deviate from the norm here.
I believe that the cure to depression, sadness, burnout whatever, is having a healthy balanced lifestyle. If you work to much, you neglect your body. If you play to much, then you neglect the finances. If you overwork-out yourself, you destroy your body. If you overdo it in any direction- it's not healthy.
It's been proven time and time again that exercise does help the overall body condition. I'm in my stage of life where I don't want to have regrets. You only one life, and I don't want to look back and think what if. I'm already at a stage where I know...I'll never run a 5:30 min mile again. If I can hold 7 min...then I'm happy. I know I'll never bike 25 mph again...If I can hold 20 mph then I'm happy. I will never bench 250...at 135 body weight again....but If I can hold 225...at 155 body weight for the rest of my life- I'll be happy. As we get older, we just deteriorate, and that's normal but I'll fight it. I don't want to be doing 15 min miles and out of breath, or barely being able to bike 10 miles without gasping, or benching the bar and fighting gravity.
The reality is that money can only get you so far. We hear about it everyday about how some rich person has depression and we think what's wrong with this dude he has everything, but the reality is that money can only go so far. After that- its just things. And do things make me happy? No.
What makes me happy is pushing myself. Pushing the boundaries. Working hard not only at work, but also physically and mentally. Life experiences, accomplishments, and earning something is better then just "buying something." I don't care how much money you have- you can never BUY a 7:00 min mile. You never BUY a good physique. You can never BUY self discipline. You can never BUY a 20 MPH bike run. You can never BUY learning a language. That's earned.
Dentistry is a hard job. What you said above about working with people, small spaces, boundaries- many people don't understand that health professionals have just a hard job. They see 32 hours a week and good money, but what they don't see is the angry patients, the complaining patients, the demanding consumer, the staff issues, the debt, the burden, the hiring and firing, the management of overhead, the non-payments of patients and insurances alike.
But at the end of the day- its a job, and if you don't think that computer science, cop, fire fighting, accountants, lawyers, medical professionals have job problems- you are wrong. They do.
What my post really means is that, if you have a balanced life, it will even out the stresses of your job. Dentistry is great in a sense that it offers a 3-4 day work week where you can have life outside work. I have ZERO excuse for not being able to bike on Fridays for 50 miles...because I have that day OFF. Alot of jobs have 5 day work week commitments and frankly don't earn as much.
So balance your life and it will balance you job. Now off my pedestal...and back to work =)
