What you consume
through your mouth, eyes, ears, nose and mind fuels you, feeds you, grows in you and flows in your veins. If you eat rubbish proteins and processed garbage then low and behold you will have cells, bones, muscle and a body built from garbage. A body built of hot-dogs will decay faster than a body built of lean meats and strong plant fibres. Bones made of BigMacs are going to break more easily. Think about it.
If you flood your mind
with news of death, destruction, violence, poverty, murder and social angst then that too will be the palette from which you paint your reality. You can output only from your input. Your mind can't help but hold what it perceives and project from it outwards.
It is imperative you consume and feed on what nourishes you, your soul, strengthens your mind, expands your dreams, fills you with belief, lights a fire of passion in your heart, loves you upwards and propels you into further evolution. Align with others who do the same and be that alignment for others.
Processed food, reality TV, mass-media
news and negativity in any form will serve to dissuade you from your true potential. Stay informed if that's important to you just don't be misinformed or (especially) deformed by it. Don't simply be a creator, that you are already whether for or against your own betterment. Be a curator also. Choose your interactions. Find your friends. Craft your experiences. Sculpt your social bonds. Chisel away what chafes at your character.
It's never too late to become whom you might have been.
...Or just go ask that hot-dog over there how it imagines improving the world.
