"Yes, its 6 months of hell, they are very hard etc".
These are typically comments from individuals that don't have a true passion for flying. These are comments from people who think being a pilot is cool and want it for the status.
If you really love flying you will enjoy every minute of it. It's not easy and you can get a be frustrated with something but I would describe it as 6 months of gaining interesting knowledge that makes you feel like a real professional once you're done.
Work hard and enjoy it is all I can say.
