I can't believe myself to be able to came up with such sentence.
"If success is determined by the amount of effort you put in, I'll be a millionaire".
It wasn't a word of wisdom, but close enough.

After much thought, I realised I actually heard of it somewhere before.
It was in one of the movies I watched or something.
"If success is determined only be the amount of efforts put in, everyone would be a billionaire."
