Some people think building credit is difficult but actually it's pretty easy.
Here are some easy ways to start building your credit
Secured credit cards - With a secured credit card, you basically deposit the money into your bank account and you have a credit limit in the amount of your deposit.
Use a co-signer - When I purchases my first car, the lender asked me for a co-signer, someone with good credit to co-sign the car loan.
Try credit with a retail store - there are many retail stores out there will offer you a low down easy monthly payment plan on computers, furniture, etc... if you are trying to build your credit make sure that the retail store will report your loan to the major credit reporting companies and buy that computer and start making your payments on time every time. That's a very easy way to build credit.
