Because it's all an impulse decision

"New Year's Resolutions" are the exact opposite of setting good goals

Good goals:

• need to be definable
  • "I will start restricting calories and target a 1lb per week loss"
  • not "get in shape"
• need to be actionable
  • "I will start making plans right now, and implementing them tonight"
  • not "I will wait till a specific time of the year"
• need to be sustainable
  • "I will adjust my strategy to work around my daily habits and otherwise be flexible"
  • not "NO MORE SWEETS"
