You are on your own when you'll have to make decision. It's hard and it's confusing because you might be taking a wrong step. We learnt from mistakes, that's what people said but yet they were afraid to make any. But the mistake that you do, is the best teacher to teach you in the future.
So don't be afraid, chase what you want to chase and gain what you want to gain. Choose properly. Lastly, please be happy, xoxo.
