Your dream is always based 100% on your not giving up on it.
There will always be moments when you feel down and out.
You may even get to the point where you want to quit.
But whether you quit or not depends solely on your determination.
On your own gusto.
Along the way you will invariably come across people that are jealous of your success.
This includes everyone from total strangers to those you love the most.
When this happens, just keep clearly in mind what your goal is and stick to it.
Do not waste your time or energy worrying about other peoples issues. As long as you are not doing anything to directly hurt or bother them then the issue exists in there head.
Wishing you continued success!
