Q:

How to properly use a credit card

I am a first time owner of my own credit card.  I got it with the purpose of building my credit to be able to receive loans for cars/house and things of that sort.  
I have amounted some student debt but now have a healthy steady income.  I also keep very close track on my daily expenses and how I spend my money.  
My plan with using my credit card is to pay it off in full when I receive the bill. 
My question lies in how I should be using it though.  
Should I use it like how I've been using my debit cards?  i.e. for lunch/dinner/coffee and other every week expenses...gas, groceries, random stops at the local convenience store... (just about everyday)
Or should I use it for only specific expenses like gas and groceries? ( rather seldomly)
Like I said, my goal is to build my credit score and I'd like to know the most effective way to do so (do more purchases on my credit card, and paying it off in full equal higher credit score?) 

A:

First of all, do not let your balance carry over and build interest - always pay off the balance at the end of the month.   
Second, do not buy more than you could afford if you were using a Debit Card or Cash - make purchases you know you can afford.   
As for where to use your credit card, in practical terms if you're following the two statements above to the letter, anywhere you would be able to use a Debit Card you can use your Credit Card instead - it doesn't have a huge impact on your credit score, but it does give you a credit identity at the very least.   
The real benefits of using a Credit Card are:

Any rewards associated with the card, like cash back or points as long as you remember to use them. 
Not having to worry about your bank account being hit if someone gains access to your card information (you'll still need to report it, but it will be the credit agency's responsibility, and your own account should be safe).   
Being widely accepted at various vendors.
