Fear of better

          This is my first post in english therefore, don't worry if find some mistakes. I'm learning english and i always wanted write a text, but i had fear while a long time because may i make many mistakes. Is about the fear i will expose here. Maybe I've afraid to bbe happy and it can affect my chooses. As i said before, i want to be physician and in my age, it may be more hard, because I'll have to desist of a large things which i get with a big effort.
