Lack of hard work definitely isn't an hindrance for grow. Having the right family name, pleasant facial structure or just being very likeable and sociable are all possible replacements for hard work.

If you aren't happy with what you have, and you aren't working hard to change it, you are guaranteed stuck. That's all.

Those things give you opportunities. You still have to take them.
