There’s a saying that the best time to plant a tree was twenty years ago. The second best time to plant a tree is right now. Time is non-refundable, so you need to make the most of it while you can. It can be daunting to start on a task that you know will take you a long time. But what would happen if you did nothing? What would your life be like in 10 years if you keep to your current course? Keep your end goal in sight. Now imagine that it takes you every day of those 10 years, but you meet your goal. How much different would your life be like?
Don’t let the overwhelm of the time it will take to accomplish something stand in the way of your doing it. The time will pass anyway. You might as well put that passing time to the best possible use.
