I worked my ass off to get where I am financially. I grew up with low income, abusive, mentally ill, and alcoholic parents. I wasn't taught hardly any life skills and I had no "connections" of which to speak. I worked hard to get where I am now (I save/invest 70% of my income a year) but I don't for a second discount luck as a big part of it. Someone making similar choices as I did can surely have a different outcome.
Plus the biggest increase in my financial status came from getting married to someone who makes just as much money as I do.
