Id strongly advise everyone reading this to treat mining as a hobby, and not a get rich quick scheme
I'm not looking to "get rich quick", I'm looking to have some fun and make some money. Basically, money is my hobby because I play professional poker. I'm just looking to leave my machine running
Read into technical Analysis and invest into bitcoins. Buy and hold is not going to make you money, but with the right strategy when to buy BTC and when to sell you can get some profits. And with your job you should be able to handle the stress

I suggest you listen to this person. Buying and holding, because the price can go insanely high one day.
