There is a philosophical proverb in Persian that says:
خواستن توانستن است
It literally means "To want is to be able to"
And it promotes the ethics of doing one's best and trying.
It encourages people to want things and to do what they can to enhance their capabilities in order to fullfil that want.
Is there an equivalent philosophical proverb/expression/idiom in English for this purpose? Because it seems that it's very universal and I expect English to have something similar.
