Say I will start today, and start today. Not tomorrow, not next week. Today. Make one small change today.
Could be to just eat 2 biscuits, instead of biscuit after biscuit (like I did, every time I'd have a biscuit, I'd have 6).
Could be to drink a big glass of water before eating a meal.
Could be to do a 5 minute work out you find on YouTube.
Just something today. Then tomorrow, do the one small change again. Maybe fill half your plate with salad and giving yourself a smaller portion of potatoes or pasta.
Maybe switch to brown bread/brown rice/brown pasta.
Maybe take the stairs instead of the lift, or get off the bus one stop early, or park the car furthest from the shops.
Make one small change today, and you are one step closer. Nothing drastic, as you have a lot going on. Just one small change. You can do it!
