1. hard work
2. opportunity
3. skill
4. luck
I believe that hard work is the most important of these four words because if someone doesn't work hard or have the drive to do so, then they will never get anything done. Opportunity is second on my list because if someone has the ability to work hard but doesn't have the opportunity to work hard on anything in particular, then that hard work and drive is gone to waste. Skill is third because skill is only useful when you work hard. One can have the skills to do many things, but if they don't have any opportunities or the drive to do anything, then that skill isn't necessary. Luck is third because being lucky is not really a thing. Everything that happens happens for a reason. It is kind of like opportunity but it can relate to anything. With luck, not much can be done and it is only occasionally that one gets lucky. It isn't a constant thing.
