Its a well used cliche but sadly not true. No matter how determined someone might be they also need massive amounts of natural talent, know the right people, be in the right place at the right time, remain fit and healthy, and have a gigantic slice of luck. The last one being the most important.For myself I am willing to live hard to reach my goals. I grew up poor and still live on a bare minimum. So struggling financially is not something that is new for me. I think that honestly is a blessing because I'm willing to endure what most are not to reach my goals no matter how long it takes.
I like to study the lives of successful people. The vast majority of them were poor, struggling to keep a roof over their heads and food in the mouths. By the grace of God they survived and did what they had to do to get where they wanted to get.
It all boils down to how bad a person really wants something.
