I've touched on this topic in many of my posts before, but I cannot help reiterating the importance of setting high goals.
What is a goal? Something you just need to write down to make your employer / teacher happy? Is it just an arbitrary list of dates and things you want to get done? No. A true goal is something that you set your heart and mind to, something you won't stop working for until you get it.
You may be thinking "Why do goals even matter, won't I progress if I just keep doing whatever I'm doing?" The truth is that you will end up SOMEWHERE, but you won't end up having much say in where that somewhere will be. By setting a goal, you are essentially making a promise to yourself that you WILL end up exactly where you want to be.
So how do you choose a goal?

Why does the goal need to be unreasonably big?
It all comes down to one simple truth: If you limit your goal, then you inadvertently limit the amount of effort you are willing to put it. If you need to make ten dollars in a day you will probably work for just a little bit, then go off to enjoy the rest of your day. If you need to make a hundred dollars in a day, chances are that you'll be working hard for quite a while. When we set out our goals much higher, we are forcing ourselves to put in a much higher amount of effort, which brings us to the next part...

While setting high goals is extremely useful, it is essentially useless if you do not follow through with action. If you set 10x goals and follow through with 10x action, surpassing your original goals will be a breeze, and when you finally make it to your 10x goals?
Then it's time for 100x
