Choose one time-consuming, non-work activity in your life and outsource it. Think of things that you can realistically outsource, such as washing clothes, cutting the grass, cleaning the house, or preparing meals.
Commit to focusing that recaptured free time on your work. Spend those one to three hours a week making additional progress on your project or focusing on business development.
You are a highly specialized creature, so utilize your comparative advantage! Comparative advantage is an economic concept that says you should focus on your most productive abilities relative to other people, and trade for resources where you do not have an advantage.
Like most well-trained professionals, your comparative advantage is office work. The small savings you earn by cooking every night, mowing your lawn, or cleaning the bathroom is nothing compared to the extra payoff you get from developing your career. Instead of spending an hour to iron your clothes, spend $20 to get them dry cleaned and spend that hour enhancing your career.
Try this thought experiment: If you could spend $3,000 a year to buy more free time, how would you spend it? By spending this money, would you enhance your ability to earn a raise of $3,000 or more? If so, the decision is easy: Outsource the task and focus on your career! In the long run, reducing task overload and enhancing work performance far outweigh the cost savings for most professionals.
