Relying on willpower
Will power is a temporary thing. Consider it a gift of energy from the universe, it helps you get all excited about your new fitness venture and it gives you that initial push you need to get started. The honeymoon stage wont last forever though, and its important to understand your new fitness lifestyle is going to be something you need to work on every single day, to keep yourself actively progressing. Willpower may come around time to time, but its never something you can rely on; instead, create habits, build your character, and learn to take action weather you feel like it or not!
