Expose yourself to as many new opportunities as possible to discover your unrealized aptitudes.
Strive to have a growth mindset. It will allow you to develop and improve your abilities.
Find your passions, things you do without noticing the passage of time.
Force your own path, along with an understanding of your happiness, instead of blindly seeking wealth, immediate gratification, or other people's definitions of happiness.
Don't plan your life when you're young because life is unpredictable.
Don't assume you're bad at something because you performed poorly in that subject in school. Standardized tests only measure one kind of human intelligence and schools only cater to a few learning styles.
Every person is special and different because of their genetic makeup (every human who ever existed in history has their own genes) and their environment (everyone has their unique mix of family, friends, and location.)
If you accept you can't predict or control the future, you will discover many new opportunities.
Experiencing positive emotions from your passion reduces stress, chronic pain, and addictions. It also improves sleep and concentration.
Finding a group of people who share your passion can be very beneficial, or even necessary, for both you and other members of the group to realize your personal goals.
