Without discipline, things take more time to get done.

What I mean by this is that things don't take longer to do. Without discipline, it takes longer to get around to doing things. Lets take a look at a really easy example how a man can improve his life. Getting into shape.

Losing weight and building endurance is one of the cheapest things to do. You don't need to spend money on a gym membership or buy heavy expensive equipment. You just need to head out the door and start running. A distance of 5k (3.1 miles) only takes 30 to 40 minutes to run. Even a man who spends 12 hours a day working plus 2 hours commuting can spare 30 to 40 minutes of time when he gets home. 40 minutes is roughly one episode of whatever on netflix and a couple cat videos on youtube. A man easily has enough time to dedicate 40 minutes 3 times a week to running 15 kilometers.

What makes it so difficult to do this?

The obvious response is that a man feels completely drained after working a tedious job all day that when he gets home, he would rather play Call of Duty than go running a 5k. And that is the pitfall.

Netflix, video games, and the internet are very cheap immediate forms of entertainment. All they require is a walk over to the computer. It is much easier than heading out the door and running for 30 to 40 minutes.

Now think about this? How much easier is it to find the time to run 5k over a weekend. Its much easier. You can play Assassin's Creed, watch a few episodes of The Walking Dead, get bored then feel like going out for a run.

On a weekend, you have a greater abundance of time, considering you are a bachelor without kids or work on the weekend. On days off of work, you have more than 14 or 16 hours to play with. On a normal work day, you could find yourself with only 4 to 6 hours of time to work with.

With much less time to work with, a man wants to relax and unwind from a tedious day rather than struggle with something to make progress or improvement in his life.

To strive for greatness and achievement, a man has to do at least one of two things. Find the discipline to sacrifice cheap easy entertainment/leisure, or free up much more time.
