“Talent without working hard is nothing.” – Cristiano Ronaldo - Portuguese international player.
When you’re feeling like you aren’t good enough, just remember that no matter how naturally talented you are, or aren’t - there is no substitute for hard work. Think tortoise vs hare - the hare thought he was better and faster than the tortoise and became arrogant. Whilst the tortoise knew he just had to work harder and won the race as a result.
