What's the most important thing you should be doing?
Why aren't you doing it?
If you answer to the second question is "I am", do not be surprised when I call you a liar. I can hardly imagine a set of circumstances where reading my blog is the most important thing you should be doing.
Nothing in life worth having comes easy. Some things, you just have to work at.
You will hit challenges along the way. You will start to ask - Is it worth it? What if I work this hard, but I only fail? Take comfort in the fact that you dreamt of a better future, and took action. Far too few even make it that far. But know that when you succeed, your reward will be worth it.
