I can make a difference by

Hi everyone. I need a little help here. I am participating in a art competition and the theme this year is "I can make a difference by..."

It can be anything we as citizens can make a difference to the country:

• Diseases
  
• Family
• Environment
• Family
• Kids
• Elders
  

Can you please suggest some ideas on what i can do.. and I want it to me something meaningful..

It can be even as simple was smiling every morning to make someones day better.. I just want to know how i can draw that to make it meaningful 😳😊

Thank you!
