We all have strength and weaknesses which means you need to have more self awareness. For instance, if you make bad food choices, then you have to address your diet and not set yourself up to fail. ย If you go home and there's no food set up, you haven't eaten during the day, no healthy snacks etc, when you get home and open the fridge and there's only bad food options, then you'll carry on eaten those foods because, 1 - your starving and 2 - those are the only options available.
Start with smaller goals and work your way up, otherwise you could be setting yourself up for failure.
