Think about what you’re doing while you’re doing it. Whether it’s brushing your teeth, eating lunch, or driving home from work, think about the good things associated with all of these tasks. This will help train your mind to think about what you’re doing, helping you to live more in the moment.
Spend time each day (about 5 to 10 minutes) where you don’t have to do anything. Use this time to focus on your breathing or observing the world around you. Look online for meditation or breathing techniques if you aren't quite sure where to get started.
When was the last time you sat down to talk to someone and neither person was holding a smart phone? Or that you didn’t spend most of the conversation thinking about what you wanted to say next? If you can’t think of a time, make an effort during your next conversation. Put down your phone and really focus on what the person is saying. You'll be surprised how much it improves the quality of your conversations.
It's easy to be negative. Try to find good things to be grateful for each day. Keep a journal and take the time each day to write something down. It can even just be a couple of sentences if you are strapped for time. Express your thanks to others either verbally or through letters and let them know how much they mean to you.
Most importantly, start small. It’s impossible to completely overhaul the way you live your life in one go. Pick one or two things to change at first, and then slowly add on to that.
