It is so natural to have doubts! Believe me, every successful person had doubts before starting some project! But they have started and they succeeded! Of course you should play smartly in life and you will succeed! As my school teacher said: “Who doesn’t risk, doesn’t drink the champagne “. Risk! Win! Succeed! ?
Anybody who’s really successful has doubts!
Your thkiinng matches mine – great minds think alike!
