Yes. And No.
When you turn off the PC nothing hurts and it cools down. But when you turn it on, there is a spike in electricity that hits the internal components. In addition, the system heats up. Over time (years, typically) this will cause electronic components stress and they will eventually fail. In addition, the heating and cooling (expansion and contraction caused by the heating and cooling) and, very gradually over time (years) make things like the RAM sticks and I/O cards slowly creap loose so that eventually you have a problem - it is a very slow process and you may never experience a problem - or you may. If you do, "reseating" (unplug/replug) is usually sufficent to get the component working again, but you have to figure out which one isn't working to begin with.
But leaving it on isn't necessarily good either. Leaving it on uses electricity (for me, in my area, it runs about $250-$300 per year per computer) and you run the risk of SEVERE damage if your electrical lines are struck by lightning or there's a severe power surge from some other source. TYPICALLY, if you want to leave it on 24x7, that's not a problem, but you should get an uninterruptable power supply (UPS) to protect the computer from sudden power failures and surges (power strips are just not that good compared to UPS systems with Automatic Voltage Regulation (AVR). The other drawback to leaving systems on 24x7 is that the components with moving parts (like the CPU FAN, the power supply and system fans and the hard drive) will wear down eventually. When they do, you can have a variety of problems from overheating of the computer to a complete loss of data (if the drive fails).
So what should you do? Probably just what you're doing. Because in either case, the chances of experiencing problems are fairly low during the useful life of the computer - 10 year old computer may not reach it's 11th birthday, but by then, it's so outdated, it should be replaced.

leaving your computer on while not in use is foolish for two reasons
1. it is a waste of energy
2. if you do not have a hardware or software firewall a hacker will log you with his probes, see that you are on constantly and maybe say .why not?
why leave yourself susceptible?
turning computer on and off is by no means harmful no matter how much it is done daily........but.....
what can cause damage is not letting cpu cool down properly between off and on again
as we know heat expands and cold contracts, so when you shut down your cpu begins to cool and persay contract........now you start again and it begins to expand ......the rapid expansion and contraction will in time damage your cpu....

you're hitting puberty quickly, if no longer already. extra testosterone on your gadget. so that you'll masturbate plenty. And no, it really isn't any longer risky in any respect. till you count number dropping your eyesight and coronary heart failure risky. Haha, only kidding. If something, it really is sturdy for you.

no, its actually good to turn it off every night, as it doesnt wear out as fast
