The single most important factor in body transformation success is mental strength. It's not genetics, it's not workout, not even diet. There is no magic diet, no magic workout, no magic pill. Different things produce different result for different people. You just need to get real with yourself, be honest, and get things done. Do what you know you should be doing. Positive thoughts lead to positive actions lead to positve results. 
There are allllwaaaayyys excuses. This is why you cannot wait! There will not ever be a perfect time to start getting in the best shape of your life. The closest time to perfect is right now. 


Does it really matter if you skip a workout today, eat an ice cream sundae tomorrow and watch 8 hours of TV the next day? Life is cummulative, meaning what you did yesterday and the day before and all the years before you are showing up NOW. So, yes, it matters. It all adds up. Think about what you REALLY want. It may seem like you want to sit on the couch right now, but a couch potato is not really what you want to be.
