which factor is the most important to your success,your knowledge,your ability,or your capitals?why

In my opinion,I hold the view that knowledge is the basic factor for me to be successful ,and capitals can promote me to receive more knowledge,together with my ability.However,abulity may be the most important to my success.without ability ,you may don't gain your accupation promotion,what's more,your knowledge will not be good enough to be used.So I am in favor of the ability to be the most important for me .
