Habits form very quickly. Like watching TV at night, going to the gym daily, putting on your shoes right foot first, etc... Good ones and even bad ones.
Human nature also makes us want to take the easier path in life. The path that is more comfortable, less hassle, not as much trouble is the path that we WANT to take, but not necessarily the one we choose.
So when you start doing things that are harder to do, it takes willpower and determination (and dreams and goals) to get you there. It's not easy, but the rewards are great! You have a sense of accomplishment that drives you to the next goal and beyond!
So when you start doing things that are easy, you don't need willpower or determination (or dreams or goals) to get you there. Make sense? The finish line at the end of doing nothing is more nothing... You end up on the easier path, but end up with everything else you try later on, becoming only harder when you try something again.
So if you decide to NOT work Monday, Tuesday and Wednesday... It becomes easier to not work Thursday and Friday. I mean, you have already blown off half the week, so you might as well just forget Thursday and Friday and just start ready to go on Monday. So if you blow off the first two weeks of the month, it just becomes easier to disregard the rest of the month and so on...
The point... It is easier to slack on what is important since it doesn't require effort (but there are no rewards). So don't give up on your goals and dreams. It is supposed to be an uphill battle, and it is going to be tuff... But when you get there, the rewards are awesome!
Has there been a time that YOU took the easier path? And expected better results?
