How to make a cycle of change, and make things better for others.

In today's society, we all live averagely. We all go through the same things over and over everyday until death. The only way to change this is to change your life. Change conditions for yourself. And to make yourself a better person.
For example. This is just 1 way that you can help the world be just a small bit better.
Next time you see a homeless person , if you can, get them some food, and maybe even put forth some of your time to make their lives better.
Another way to make the world that much better , do what you want to do with your life. being stuck in a job that you don't like, probably doesn't make you happy. Find a something that you can do, that you want to do. If you don't want to retire from it, then you might not like it.
Now, its not all about jobs.
Hygiene. It can make you feel better, and make you more confident. Don't hold back on taking that shower or brushing your teeth. With better sanitation, your life can be better.
Eat healthily. If you are like some, you might eat TV dinners for dinner or lunch. That isn't exactly healthy every day. Maybe get some chicken and lettuce, tomatoes, etc. and make a salad for dinner or lunch. Its healthier, and will pay off.
Last, but not least. Help others around you. If you feel good, you radiate that vibe of well being. Radiating the vibe of well being spreads it to others. And it starts a cycle of being happy, healthy, clean, and living life however you want.
I am not here to tell you what to do, as i'm 13, but it'd be my best guess.
