Sometimes in life we do things for the wrong reasons but they turn out to be one of the best decisions in our life. For example, one of the best decisions in my life was starting to volunteer for a certain project because someone who picqued my interest happened to be involved in that project too! Although my interest waned after a while, I met some wonderful people who were to become lifelong friends.
So if you have any doubts and question yourself about why you are doing something, if it is a good thing overall then it will lead you to uncharted territory that you never imagined. Go for it and let destiny take you where you were meant to go.
