Give me six hours to chop down a tree, and I will spend the first four sharpening the ax. – Abraham Lincoln
I am not suggesting that you spend 66% of your time exercising, but you – absolutely, positively – must exercise some, consistently.
Is it hard to do? Yes and no.
The actual doing is easy, especially if you gave a great playlist.
But the getting to the doing can be hard.* It’s easy to procrastinate – trust me I know…
Regardless the imperative remains.
As Phil Knight might say: Just do it.
* One thing that can help is to take some time to get clear on why fitness is important and useful to you, personally and authentically. Doing this will help you develop the sustainable emotional energy you need to get started with, and continue, a physical fitness practice.
