What unusual habits have you developed that have significantly improved your life?

I developed a habit of going for a daily walk, which has helped me increase my physical activity and clear my mind.

I started practicing gratitude journaling every night before bed, which has helped me focus on the positive aspects of my life and reduce stress.

One habit I developed was taking cold showers in the morning, which helps me wake up feeling refreshed and energized for the day ahead.

Practicing mindfulness :)

Journaling has helped me a lot

I started using a foam roller to massage my muscles, which has helped me reduce muscle tension and soreness after exercising.

Proper estimation of a project and time it with a count down timer during execution to avoid spending too much time on a single task

I used to track my spending, and sometimes I will be wasting 30 minutes or more figuring where the $1.70 went, what did I forgot. I always convince myself 'it's not about the money, it's where the process went wrong that I do not recognize'. Eventually I realize the 30 minutes I spent thinking (and reflecting) doesn't worth the value, I could easily gain more than $1.70 in 30 minutes by letting it go. TLDR: If you track your finance (how you spend), don't be particular with tracking where every single cent goes. Just having a good grasp of how you spend will already solve 80% of bad financial habit

I started using a standing desk at work, which has helped me improve my posture and reduce back pain.

I started practicing intermittent fasting, which has helped me improve my digestion and increase my energy levels.

This may sounds dumb but if works great for me. Before I go to sleep I prepare my outfit for the day after. That way when I get up in the morning I don't have to worry about choosing an outfit and it saves so much time!

Probably meditation and golf. (Not simultaneously, though.) LOL.

I developed a habit of setting daily intentions every morning, which has helped me focus on my goals and stay motivated.

I developed a habit of taking regular breaks throughout the day, which has helped me reduce stress and increase my productivity

I started drinking a glass of warm lemon water every morning, which has helped me improve my digestion and boost my immune system.

I took to competitive cycling as a sport and bicycle touring. My holidays revolve around races or touring and exploring, only to come back healthy. Meditating and Gratitude practice 100% turnaround for me.
