Apply the 80/20 rule to almost everything in your life. What is Pareto's Rule? It simple means that 80% of results come from 20% of the efforts.
When you apply this to both your work and personal life, you will find balance and learn how to prioritize tasks that have the biggest impact in regard to results. Some tasks may take longer to implement, but the result has a much larger impact than doing a bunch of tiny meaningless tasks. Remember to look at the big picture and figure out what will get your results!
Do not underestimate the power of a meal plan or meal prep. Spending those 10-15 minutes and simply writing down what you want to eat can save you from making some poor last minute decisions. It also help you eat better, support your metabolism and save money in most instances!
Remember to always look ahead by 1-2 days to make sure you have ingredients on hand, and marinating time is accounted for and batch cook things like rice or grains which you can use all week in various dishes
