We all have doubts, that is a part of living. At some point in our lives it is important to face them and see what are they really? Fear? Excuses? Obstacles? Self-limiting thoughts? Safety valve? They are a combination of all these things. No one living wants to see themselves screw up or make a fool of themselves. We all want to be respected and valued for who we are. The doubts are there to tell us that we might not be doing something so brilliant or spectacular as what we think. Fear tells us that if we fail we will be worse off than before. We are afraid of losing what we have, excuses arises to lull us back into our comfort zone, making obstacles seem even more unsurmountable than before. Let's face it, if you really want something it involves risk and working for it. A gold medallist spends countless hours preparing for competition as does the person who comes in last place. They train hard and push themselves to be the best they can, but do not always come in first place. It is a good feeling when you realize that you have improved(without doping) in spite of risk of injury. In the end the Gold medallist might get more recognition, but everyone has won something from it. Pushing yourself to find your boundaries teaches you that you can get better and improve your skills. There will be always be critics, often the hardest critic is yourself especially when you do not reach your goals. Anyone can give up, you do not need a Phd to quit. Be determined, face your doubts and show them that they are mirages, that will fade with your growing self-confidence.
