If you struggle with a specific task, do the little things.
That will save you time, and help you focus on your work.
For instance, if you’re writing an article, this is what you can do to focus and save time: pick the category, schedule publication, find a title, sum up the main points, download pictures to illustrate your ideas, and so on.
If you’re designing a website, you can: find websites you’d like to take your inspiration from, choose the main colors, define the structure, list the most important features, set the ideal rules and dimensions for every device, pick a few fonts that suit the brand’s tone, and so on.
In the end, all these little things will become tiny achievements that make you feel like you’ve made progress. And that will help you work and focus faster.
