What habits have helped you save more time?
Carrying a Notepad and Pen with Me All the Time
Capturing your ideas or simply to-do items on paper saves you a lot of time.
If you don't capture them, they will wander around your brain and pop up in the most inappropriate moments. You will dismiss them focused on the task at hand and they will be back again and again.
It's more of a tool than a habit. But thanks to this tool I no longer habitually visits websites that distract me.
I love to read news online, I love to check my stats all the time... but it serves no real purpose than distraction from boring or tiresome work.
Setting Daily Priorities
Every morning I write down no more than 5 items I want to deal with on a given day. They are my point of focus. When you know what you want to do, you don't do things that waste your time nor you procrastinate as much as usual.
Have a list of to-do items that you can do within a few minutes and do them when you have a moment to spare: while commuting, standing in a queue, waiting for an appointment and so on.
Meditation, Journaling and Practicing Gratitude
All those activities are working as catalysts. They enhance everything (or just too many aspects of your life to enumerate them all).
You don't waste time on them activities. You invest your time. When you are more grounded, happy, healthy and focused, you are more productive as well.
Heavy Intensive Interval Training
I exercise about only 5-10 minutes a day, but I do it very intensively. It not only saves me time on hours of cardio, it also keeps me fit and healthy.
