If you do then the rest of the day will feel lighter and easier. You will feel better about yourself and more confident as you move on to other tasks.
If you have trouble getting started with the most important task then just make a deal with yourself to work on it for 3 minutes. Then you can stop if you like. But you may not want to once you have gotten started. That seems to be the case for me most of the time.
Getting started is most often the hardest part. So make that part easier for yourself.
5. Go slow.
When I go a bit slower it becomes easier to fully focus, to keep the stress down and I most often do a better job with something the first time around. I work with
more clarityand I do not get stuck in doing busy work very often.

It may feel like I’m not getting enough done but at the end of the day I usually get more quality work done than if I tried to maintain a high speed through the day. Partly because the lower stress levels keeps my mind fresh and energy up even through the last few afternoon hours of the workday.
6. Work out.
My favorite time to do some free-weight exercise is about an hour or two after breakfast. By doing this 2-3 times a week I boost my energy and hormone levels. This makes the rest of the day lighter and I feel more decisive. Inner doubts and tensions lessen and my mind becomes more optimistic.

I highly recommend doing some kind of exercise in the morning. If you can’t go to a gym or work out from home early in the day then maybe you can walk or bicycle to work or school.
7. Do the right thing in some small or big way.
This one boosts your self-esteem. It puts a spring in your step and it at least makes me feel happier. So do what you deep down think is the right thing.

A few examples that may resonate with you:
Perform a random act of kindness. Hold up the door or point out the way for someone who seems lost.
Help someone out practically or just by listening.
Encourage someone.
Get started with putting a dent in the most important challenge in your life.
Build upon just a small step, a small thing if you like. Start building an upward spiral of positivity and good feelings within. And then take further steps upward. Towards what you know you really want and you know are the right things for you in your life.
