Ultimately, the only person that can truly make a difference in your life is yourself. Others can inspire you to want to make healthy changes, but at the end of the day, that shit falls on you to put the work in and actively make those changes. Otherwise it's all for naught.
Life is beautiful, but it's just as unfair as it is amazing. There are just as many valleys as there are peaks. Don't wait for a miracle or a handout, BE the change you wish to see in your life.
