1. Distract yourself with something more pleasurable.
2. Try to work harder and use more effort.
3. Strategically work "stronger" by letting your motivation rise, which will radically increase your power and output without a sense of depletion due to overwork.
I choose the third choice because it more allows you to tap into your true potential. Trying to push yourself up a mountain, especially a boring mountain that tires you out from the start, can be very unsatisfying to the spirit. That's not to say, though, that you shouldn't do things you don't initially love doing such as work tasks etc. but that you can upgrade your experience and creative output, allowing the experience to seem more effortless.
When we're in the flow, work is less work and more of a harmonious series of actions. You don't have to be bound by the monotonous aspect of the task, pulling you into feelings of boredom and low energy. You can choose to rise higher and feel a good about it.
Think of something that instantly draws your attention to a higher energy state. This is especially powerful if it's something you want to attain and you feel inspired about. Then add in a potent superfood or herb that you feel works well with you well on an energetic level. This can help to amplify those feelings of enthusiasm so that you can sustain them for longer periods of time. Many of them naturally encourage subtle increases in feel-good neurotransmitters that allow us to access creative states of mind more easily. This can PROPEL you into a state of utter flow.... Where the moment appears to be more of a clean slate and opportunities seem to be in view. From there, just the notion of a sense of possible progress toward your creative envision can be enough to fuel your work day as long as you remember to actively keep your vibe up and direct that energy toward your task.
