@singingislife28,
Our Grandparents.
Bless, they just want us to be who ever we want to be in life, no expectations, no push, no judgement.
Our parents (some) want us to be receptionists, Dr's someone, never anything to do with chances, because they really never had the chance to take any and well, there can be no income involved and what if you fail?
Fear.
Go for it, if you dream a dream, that dream can happen, remember you may fall and then start again, my suggestion as an ex singer, model, that well they wanted that "couch" think about that too, is to have a part time job, mine was in restaurants, you can always work in those and make money, and follow that dream.
They just have fear what if. Grandma doesn't she believes.
Lastly BELIEVE and never give up, if you fall get yourself up again and keep going only the strong make it.
Good luck from an ex singer x
