Replacing a bad habit with a good habit will show you better results and with better results come a greater chance of repeating the new behaviour. Just makes sure you give it time, as the results won’t be immediate.
Your actions and behaviours determines your results and consequences. What actions can you change to help you get better results? Can you start today? Absolutely. Will it be fixed today? Absolutely not! It takes time. You owe it to yourself to do it.
