You can't change your life in one day. Not even in one month. It takes time.
Learn how to set goals. Goals should be S.M.A.R.T.:
S - specific
T - timely
Never say, "I want to lose weight." Try this..."By cutting out sugar and alcohol for the next 5 days, I will lose 1-2 lbs." Instead of, "I'm going to workout more." Try..."Tomorrow I will wake up at 7am and do interval training on the treadmill for 20 minutes before work."
Yes, it's good to have a big picture idea of where you want to go. But you have to lay down the plan to get there. Make some SMART goals for this week and WRITE THEM DOWN!!! Very important! Then follow through!
Once you complete your goal, make another, then another. THEN...6 months down the road from now you'll look back and be amazed at how different your life is becoming. But it all starts with small victories. Tons of small victories in a row lead to major changes.
My SMART goals for this week. "To lose one more pound and to be more productive and clear headed, I will abstain from alcohol from now until Saturday night. Then I'll indulge in one glass 'o red to celebrate my victory!" "To push myself physically and to become a better runner (my weakest link!) I will spend 20 minutes extra working sprints on Monday afternoon and Thursday afternoon of this week."
Try it.....set a SMART goal!
