You have the power to change to the world, but you can only do so by changing yourself first.
Is your current life monotonous? Do you feel as if your life has nothing new to offer? Does this anyone you or turn you into a chronic complainer? If yes, it is because you have stopped trying new things. You are so used to doing the same this that it is almost like you are a robot. Let me ask you something, if you never give yourself the chance to try new things, how can expect your life to change? How can you expect your life to go in a different direction than the one it is currently going in if you do not change any of your thoughts actions or behaviors? Seriously, How? Do not even bother giving an answer to that, because I know there is none. You must know that you are the creator of your own destiny. I you want to remain stuck in a rut, then by all means do so. If you want to, change yourself and your life for the better, to experience new and wonderful things to be truly happy than make change. If you expect your life to just change while you are lying in bed or setting on the couch, you are sadly mistaken and in for rude awakening.
A healthy mindset is one that is stimulated and energized. One that remains optimistic and seeks opportunity in all its ventures. Good news, doing new things is the best way to achieve this type of mind.
