When you’re struggling to find motivation you can look for long term or short term fixes. These long term solutions involve changing your lifestyle in order to develop productive habits and self-discipline. Whilst long term solutions are the goal, if you need to get something done then short term motivation is the way forward.
If you need to get something done it sounds counterintuitive to not begin right away! But in taking the time to go for a short walk you can refresh your mind and energise yourself for the task at hand.
Commit to just one thing. Write down one task (writing is a good visual reminder) and focus on only that instead of splitting your time and energy up.
