I've always had this problem but a few months ago I borrowed a poster from my dad (career Marine, epitome of focused, determined and successful) and it's helped me keep my focus. It gets me out the door to run (I've never worked out before), it helps me pick up the statistics books I have (course I failed in college) and and it reminds me to do my best at work everyday. It's quickly becoming my mantra and maybe it will help you but you might also find it to be extremely trite so take this for what it is.

CONSISTENCY By George H. Allen (Only NFL coach to never have a losing season)

Consistency is the truest measure of performance. Almost anyone can have a great day, or even a good year, but true success is the ability to perform day in and day out, year after year, under all kinds of conditions. Inconsistency will win some of the time; consistency will win most of the time.

Consistency requires concentration, determination, and repetition.

To be at your best all the time, you must: Take nothing for granted. If you aren’t “up” every day, some thing, or someone, will knock you down. Take pride in what you do. The things you do well are the things you enjoy doing. Take setbacks in stride. Don’t brood over reverses; learn from them. Take calculated chances. To win something, you must risk something. Take work home. To get ahead, plan ahead. Take the extra lap. Condition yourself for the long run. The tested can always take it. Don’t take “no” for an answer. You can do what you believe you can do.

PS…Celebrate after the victory!
