Be yourself and do what makes you happy. Your life is to make you happy and to fulfill your needs. When you are down or something happens in your life negatively you should always try to make a change for the better. An example would be me breaking up with my boyfriend, i started to go to the gym, i got a new job which includes more hours (less time to be sad). You will be surprised when you start doing you and working on your life people will pop in and out. The ones who matter stay. Take chances because even if you fail you at least tried and got it out of your system. Live life everyday like it is your last.
