Just go for it!  What is the worst that could happen, you fail?  Self doubt deprives you of the possibilities.  Sibling rivalry, jealousy and self sabotage are all negative reflections associated with competition and can prevent many of us from not engaging, a symbolic speed bump or barricade that stops our momentum before it has a chance to start.  Understanding the value competition provides becomes a limitless resource in discovering oneself.  Now it is important to recognize, that achievements don't define an individual, rather the virtues they display speak of the character and integrity that embodies that person.  There are risks in life that potentially could lead to huge wins, regardless of the outcome participating contains all the enlightenment.  Innovation would be lost without competition, appreciate that there are others better than you.  Take the opportunity to grow closer to those in place you want to be, indirectly they will help unlock your potential.  Alaina Rissling and Rhys Sept explore why, not being a bag of chip and all that, is acceptable.
