I think you are very lucky to know what you want to do in life at such a young age.
When we say, 'what you want to do in life' it means what career/life goals you have for yourself. People do not normally know what they want when they are young. By saying 'such a young age', the word 'such' puts emphasis on the person being really young and already have their head screwed on (sensible and knowing what they want).
what you want to do in life'（人生でやりたいこと）と言う場合、あなたのキャリアや人生の目標を意味しています。若い時にはやりたいことが通常わからないものです。'such a young age'という表現では、'such'という単語で、その人が非常に若いのに、すでにしっかりしている（賢明で望むものを分かっている）ことを強調しています。
Knowing yourself at an early age will allow you earlier self-realization, this will help reach your goals sooner.
Realizing your ambitions early on in life is a great advantage because you have more time on your hands to make them a reality.

They are more likely to reach their goals than someone who only learns of their ambitions later on in life.
Stencil: outline
Self-realization: knowing yourself on a deeper level
Ambitions: powerful desire to achieve something
