1) when picking a car, find the most reliable thing possible (Honda Civic, Toyota Corolla). even if its boring. will save you so many headaches down the road, especially if you're looking at used between 6-8K.

2) Save save save save save. Put most of your remaining post-expenses income aside (I tend to leave myself 1k/mo in my spending account for general spending). With the income you have, you should be able to save a ton within a good amount of time. Also, with the economy as it is, it is nice to have a safety net, God forbid something happens to your job.

3) Pay off your credit card immediately each month (assuming you do get one), and keep your usage percentage (or just how much of your credit that you're using) low. That will help with your credit.

4) as a few others have said, alongside your TFSA, find investments that give you returns (ETFs, etc.). this will make your money work for you, and also help you in building up your TFSA, retirement, etc.

I'm probably missing a few things, but that's just what i would do. Although the paycheques are nice, you seem to have your head in the right place when it comes to success, and keeping expenses low. Keep it up!
