How can I get work and change my life ?

[Connie]

you are not alone. The world is big and competition is the main rule of life, at least it seems to me

to become a big IT-company when you are 21 years old? you are young enough to start and to reach this goal in some time

There are a lot of tutorials for "self-marketing" in the business, do a websearch and read them

the best start is always:

- do some good websites for others, show your potential in these sites
- do a good website announcing your work
- use the websites as reference
- open your ears in your neighbourhood, I am sure many people need a good website
- check the quality of websites of local businesses or organisations, and if they are poor convince the people that you can do it better at a reasonable price

good luck
