If got a big project coming up, break it down into smaller tasks with deadlines. Don't be overwhelmed by the jumbled mess in your head - list them out, and order by priority. Tick them off one by one, or you'll keep reminding yourself and risk stressing out over what's pending.
Set timer for 15 minutes to power focus on one task, then take a short break. This helps to maintain momentum with impending deadlines cos you're not thinking long term. Plus, there's something about knowing you're working against the clock that keeps you focused. During the break, treat yourself to a stretch or favorite snack before starting again!
Batch similar tasks together, like scheduling back-to-back meetings or doing one big grocery run. You save time and effort cause everything's in one go - think of it as efficient, concentrated productivity. And less travel time means more time for you!
Clear distractions from your workspace. That pile of papers or pending emails can bug you mentally, so clear them off your desk and close those browser tabs. Outta sight, outta mind really works, man. You'll get that sense of clarity and focus back.
