I still snoop at my christmas presents help?

im 15 and have always loved christmas, christmas eve i stay up all night excited like crazy, and wake up my parents and sister at 7 or 730 to open up presents(my dad wakes up also) anyway i kinda already knew what a few of my gifts were because i asked for a couple specific things. but i still cant help snooping. i looked on my dads ebay to see whats he bought. i will not to do it again because i got mad at myself for doing this, but just in case i wanna do it again what i should i do. and is this bad that i still get this excited over christmas even at 15 i mean the tree is going up next week and im counting down the days finishing off on some on ornaments( i like to make ornaments its always been a hobby of mine) or is this fairly normal tell me what you think
