You are in control of what happens to you in your life. Sure there may be a few things that happen here and there that aren't but if you really look at your day, the majority of what happens is completely up to the choices you make.
I hear this a lot of the time "I would love to have the discipline like you and eat healthy and train but I can't". Well you can. You just haven't decided to do it. What you put in your mouth is completely in your control. Training, that's easy. Start moving. Stop sitting around saying you don't have time. That is a poor excuse. If you give me your schedule I will find plenty of time for you to cook a few meals and fit in some training. People are wasting time sitting on all these social media sites, watching T.V, just doing unproductive things but feel like they have no time.
If you really want to change your life or achieve a certain goal then you have to find ways to fit the things in that need to be done. Go to bed earlier and wake up earlier. There is a simple solution. But you know what people don't do it. Why? I don't know. They don't really want whatever it is bad enough? It's not a priority? That's for them to figure out.
For me it is about being in control of yourself. Once you have decided you are in control, your whole life will be better. If you don't like your job, then change and get a new one. If you want to stop drinking alcohol then just stop drinking it. It is really that simple. The more you do the things you want to do and don't cave in to the pressure of the majority, the more happiness and success you will have.
Simple, but not always easy. Decide and do.
