Dont worry young fellow,at the age of 23 you are doing well above average ,those people flying an airliner at 18 or 20 ,are the "lucky ones " found in all aspects of life ,but I bet they did not have to pay for the training they did not learn a second language , they dont have a university degree,and of course they did not have to build flight time in remote places risking their lives ,they just pay ,and pay and pay .
So dont worry whatsoever ,you have all your life to make your dream come true ,and will enjoy much more than the younger colleages .
