We can change our emotional state by focusing on our physiology rather than our emotions. Using the following tricks can give you energy and an emotional boost to stay productive.
Put on some upbeat music.
Stand up and stretch. Try to reach the ceiling. Get on your tippy-toes.
Take several deep breaths. Oxygenating the blood make you more alert and awake.
Get your body moving. The more vigorous you can move, the better. Go for a run, a bicycle ride, or simply a walk outdoors. If you do it for long enough, your brain will release endorphins that elevate your mood.
Focus on the positive. Think positive thoughts. Give thanks for what you have rather than complaining about what you don't.
If you have a goal of writing a book, and you focus on intensity, you may lock yourself away for thirty days, and write eight hours a day. It will require a huge block of dedicated time and lots of motivation.
Instead of writing a 50,000-word book in thirty days, write 500 words a day for 100 days.
Instead of going on a two-week fast to get in better shape, eliminate sugar and processed carbs from your diet.
Instead of waiting to start your business until you've quit your job, set aside three hours a week and start a side gig.
The intensity approach is more dramatic but slow and steady wins the race.
Your manager may not put in the effort up front to articulate the expectations she/he has so that you're on the same page from the start. It may leave you guessing what successful completion might look like, and then frustrate you both when you think wrong.
To be fair, at a certain level of seniority, it becomes more reasonable for a manager to expect you to know what you're doing and work out the details by yourself. But even then, a good manager knows when to invest the time to get more aligned on those things.
