ability to succeed

hi see i am so lazy! i posted two post on the same day! lame right? do you know that that everyone in this whole wide universe have the ability to succeed but it really depends on the creature(like me) if he or she wanted to put in the efforts so that he or she could succeed or improve in certain areas! take Neville Longbottom in Harry Potter as an example! he could not do the disarming charm which is Expelliarmus at first but after putting lots of effort trying he finally succeeded!
