Loving your work does not mean you don’t need to work hard.
Work is defined by the expenditure of energy. It doesn’t have to be unpleasant to be work. It needs to expend energy.
When you love your work, you expend your energy working hard at the work. Because you are enjoying it, you aren’t wasting any energy convincing yourself to do the work or fighting your resistance to doing the work.
Remind yourself that you love this work. Remind yourself of what it is that you love about it. Focusing on what you love about your work won’t make it less hard. It will significantly reduce stress.
Setting boundaries helps you bring your best self to your work. Don’t make the mistake of working yourself to exhaustion to make the work you love feel like “hard work”.
