If you want to earn a living doing mining you are going to have to work at it. Mining requires a lot of time spent in forums reading and learning, then once you have the capital invested in hardware you have to tweak and tweak and tweak. There will be less work with the asic miners but by the time your order is fulfilled in a few months and you actually start mining with it the difficulty will be through the roof as compared to right now, so your profits will not be as high as they look like today. As time goes on and the difficulty continues increasing then eventually you will earn less than the electricity you spend to run the hardware (with asic mining this is less of a concern).
Additionally, if you want to earn a living you are also going to have to continue scaling up, which means a lot of investment which means rather than taking your earnings as pay, you are going to have to roll them back into more hardware so you can earn more so you can get more hardware and the cycle continues. Its the only way to stay ahead of the curve. So yeah, good luck and have fun, I hope you can figure out a strategy and make a good go at it!
