Hii everybody here

I was using computer from age 7 till now i'm 20
but in the past 2 years i used linux ( Ubuntu )
and i have a small Q !
while the linux is open source so how could I make changes to the application !
for example any application for mail ! how could i improve it by myself as its open source so i can change in it ! am I right and thanks aloot
