Slow down to enjoy life more and feel less rushed. You’ll pollute less too.
Do less. This is both a happiness and productivity tip. Doing less will make you happier, because your life won’t be so hectic and filled with stress. You will have time for things that give you pleasure, for the loved ones in your life, for life itself.
It’s also a productivity tip: if you focus on the essential tasks, the big ones, the ones that will give you the most return for your time, and eliminate the rest, you will actually be more productive. You’ll get fewer tasks done, but you will be more effective.
Slow down. I feel that life is much more enjoyable if you slow down. By doing less, you can actually get more done, even if you work more slowly. And when you’re not working, you should definitely try switching to slow mode. Drive slower (it is so much more relaxing), walk slower, eat slower. Slow Down to go faster.
Practice patience. If you easily lose your temper, you can become more patient with these tips. Once you’ve developed this skill (and it’s a skill, like everything else, not an unchangeable inborn trait), your life will become much saner and you will be much happier.
Practice compassion. This may be the most important tip of all, in my opinion. If you were to choose any of these, I would choose this one. The first part of compassion is empathy — and this ability to understand how others feel can be developed through practice. This one thing can bring true happiness to your life, and the lives of those around you.
Find your passion. Another indispensable tip. This might be the second on my list of priorities. Find something you love to do, and your life will become immensely improved. You will love your work, the thing that you spend 40 hours (or more) a week doing. I know I love innkeeping and horsekeeping. You will become more productive, procrastinate less, and be less stressed.
