Smile at yourself in the mirror
Just after you brush your teeth, look at yourself in the mirror and smile, holding the smile for 10 seconds, suggests Quora user Nistha Tripathi.
Dr. Robert Zajonc, a renowned psychologist, believed facial action leads to changes in mood, and in a 1989 study he found that participants who watched themselves smile in a mirror experienced a greater boost in mood than those who simply smiled.
Walk more
Multiple Quora users suggest walking to work if you can, taking the stairs, walking around the office when you're stuck on a problem, getting outside and walking during lunch, and walking home again.
The exercise isn't just good for your body. It can also boost your energy levels, creativity, and mood, too.
Write down the day's most important task
Also known as 'eating the frog,' decide on the one task you must perform that day to be successful and do it first thing when you get to work, writes Quora user Patrick Mathieson.
Make your bed
Starting your day by finishing something and doing it well provides a small self-esteem boost early on. And when you come home tired from a long day at work, there will be nothing between you and a good night's sleep, says Quora user Rizwan Aseem.
Say 'no'
It's a moment on the lips, but saying 'no' can save you so much more time than that.
'If you do not want to do it, do not have enough time to do it, see no benefit in doing it, just say, 'No,'' writes Quora user James L Moyer.
'Refusing other people's unreasonable requests may seem lazy, but it is absolutely the smartest way to manage your time and will free up the needed space for you to accomplish your personal goals,' Moyer writes.
