1. Intermittent Fasting. I had gained a lot of weight after an accident. It helped me get back into shape. I was always a very active person. So I never had to watch what I eat but late twenties and my injury forced me to watch I eat. I'd often feel bloated, heavy, and tired. Fasting regularly for at least 18 hours was something I had to work on but it's just second nature to me now. Feel a lot more energetic and light :)
2.Picking hobbies that I'm serious about. I've always been one of those people that would pick up something and drop it after a couple of months after getting that initial sense of achievement.
I didn't change this habit right away. Instead, I actively searched for something that would really, really click. Landed on drawing and downhill skating. I've been skating for 2 years straight now and drawing is catching up. I think around 6 months now.
Having something you're really passionate about outside of work, man, it's like a different kind of medidation. Especially something as dangerous as downhill skating. I started it as a fat and out of shape, tech guy in his late-twenties. The improvement I could see was what kept me motivated through the scary novice times where I'd get injured frequently. Honestly it was really scary. But now, it's a great outlet where I can get into a hyper-focus state and just exist. Because if you don't do that, you might actually die, haha.
3. Not a hack but something I've noticed in many part of my life is that the more relaxed and loose you are, the more precise you can work. I had learnt this while learning to play the drums back in highschool but never thought about applying this to my daily life. The realization hit when I was learning to draw. But it works in almost anything.
