What you are today is the choice you made yesterday.
Being humble doesn't mean you lose; it means you have won. Give the victory to others.
Find yourself. Be with yourself. Fail and then achieve.
The next time you face a challenge, remember that the cost of success is far cheaper than the price of failure.
Be different, be altruistic. Be strange, work for others in response to their harm. Raise eyebrows, be generous without agenda.
The minute you say "I can't", it is another wrong affirmation to your subconscious that you choose to lose.
