Clarity gives strength. Knowing the why will keep us on track when other things try to de-rail our best intentions and desires.
Figure out what it is that motivates you and keep it in mind. For some of us is health while for some of us it might be vanity and even for some it is a passion for life. There is no wrong answer just get your answer. Why Do You Do It? Why do you want to loose the weight? And once you know the why keep it ever present to give you strength on the moments that excuses sound good as if they were reasons.
Keep focus and keep going. All the best to you all.
