First thing to remember to keep your self motivated to lose weight is to ask yourself why you started doing this. You don't do this because you just want to impress the people you want but rather you are doing this beacuse you need to be healthy and prove to others that you can be a better version of yourself. Everymorning affirm your self with a quote that motivates you. "I am worthy of this, I am Limitless, I can do this,". Never ever listen to people that are discouraging you! Listen to yourself, because you are the one who is responsible for your self. No one can make changes on your. It's only you who can make you a etter version. 2nd is do not expect perfection but instead look forward to a progress. He buddy, no one can lose a half of their weight in just a month. Be realistic, It takes a lot of time in reaching your goals. But staying determined, you can do it faster. It took me almost 8 months to loose 30 kg of my weight. I never lose determination because I want to be better. If you think can't make it, just believe and everything will go on it's right path. Goodluck!
