"If you are trapped between your feelings and what other people think is right, always go for whatever makes you happy, unless you want everybody to be happy except you."
Being happy is ultimately a decision we must all make in our lifetime. Letting ourselves be confused by what other people want for us to do with our lives, and living out what we know is right in our heart is something that we can't allow. In fact, it is probably most beneficial if we at least create some distance between the people and ourselves in our lives that don't support our dreams.
If you allow someone who doesn't believe in you to pull you away from your dreams, then they will. Your happiness is your own to find. Do the things that are pleasing to your heart, and work hard to inspire and bless others. The life you have should be cherished, and should be treated as a gift by everyone who is given it. Live life as yourself, and as yourself only, for it is the only way you will gain true happiness.
Be happy and may God bless you and yours.
