I definitely pushed myself harder today - after a 3.2 mile run, I was exhausted, semi-nauseous, and had a splitting headache (the human body is so weird!). Running is becoming more and more of a mental game now - every time I am out there, I'm setting different goals - "Run until the stop sign, make it to the edge of that street, catch up with the couple running ahead of me" - and sometimes, it is as simple as "Just run so you can get home faster and plop down". I still love running without headphones - specially now that spring is here (it snowed yesterday so not too sure about that), it is so nice to hear the birds chirping and the wind blowing through the trees. The first two miles weren't bad at all - I think my body is now used to that. The last mile was just brutal. Guess the end goal makes it all worth it? The most brutal part, I must say, was when I ran by a restaurant and got a whiff of delicious fries. It took all my will power to not succumb and keep running (I probably shouldn't run with my credit card in the future - rationalizing myself out of this one was very difficult thanks to the fact that I had an avenue to pay for the fried goodness).
Motivation is a funny thing - different "tricks" work at different times. The key is to keep finding something - the minute you don't have a need/want to find a source of motivation, you have already lost out. There are always lulls - periods when not doing anything just sounds fantastic and probably IS fantastic - the longer the lulls, the more difficult it is to get out of them. When I travelled with my Tepper MBA folks to Morocco this past couple weeks, there was a couple in the group that went running every day. I regret not going with them, (yup - I was lazy.) but it was inspiring to see them not use vacation as an excuse to not run.
Bottom Line: Never stop finding your sources of motivation - the more the merrier.
