Try LESS planning, MORE doing.
Drink LESS (better yet drink no) soda, MORE tea (sugar free, of course).
Eat LESS junk food, MORE salads.
LESS doubting, MORE believing (in you, and what you can achieve).
LESS lazing around, MORE working out.
LESS being weak, MORE confidence in reaching your goal(s).
LESS hating your body, be MORE loving towards your body, it's yours after all!
