@keepy While that is a crazy rule to have, I do understand the discipline this will teach which will be absolutely crucial for later on in life.
Most kids don't get the lesson in discipline like you're getting, your father is teaching you to have a set schedule and to sacrifice a lot of things to keep at it.
While at the same time it will build up strength and having the ability to sacrifice things close to your heart, to gain and move closer towards something much bigger.
While I'm naturally inclined to the idea that after 13 the teen should decided on their own what time is right to go to bed by, as long as it isn't unreasonable.
I do like this idea though, while you are seeing it negatively right now in the bigger picture your father is only thinking for your future self and wanting to get the best out of you.
Don't let this think ill of your father, he wants the best for you, always.
I just hope you can gather the lessons being given and use them to your advantage later on in life, trust me this world is a dog eat dog world. Some of those closest to you are only there for certain period of time, some shorter than others and you will have people close to you that will do you wrong.
Having the ability to see through the lines and knowing true values and what someone's worth is, use these teachings to make the right sacrifices at the right times.
Lastly always surround yourself with positive people, those who are negative will only drag you down and abuse the niceness of your heart... it isn't worth it.
