I got the idea for this short blog from my time spent on the track this weekend. 22 hours gives you a lot of time to think and take in all the scenery. When I was running I noticed a lot of people showing up to the track for about 10 to 20 minutes and then leaving. The people I saw would run a mile or less and then leave. Let me make this clear: I'm not saying this is a bad thing! In fact, running a mile is great, but eventually you need to build off of that work and add more mileage to truly improve.
The idea of pushing yourself goes along with consistency in order to attain success. Consistency without any drive does nothing. You may get better for a little while, but eventually you will stagnate. I know in my life when I stagnate, I lose that drive and whatever I'm doing gets a lot more difficult.
It doesn't matter if it's running or not, if you don't keep putting yourself in tough situations there will be no true growth. So take that mile and make it two...and then three. It may be tough, but it WILL make you better in the long run. Who knows, you may find out that you're pretty good at something when you add difficulty to an activity and you're forced to overcome that extra obstacle!
