Here are some fun ways to celebrate your birthday.
Explore (探索) a new place
Generally, people celebrate birthdays at home or at a reserved (预订的) place. So, I think you should do something different this time. You can just find a few random (随机的) places around your city to visit and explore.
Celebrate with nature
If you want to do something unique (独特) that you haven't ever done before, then go for this one. Find a place that is close to nature, like a valley (山谷), riverside, mountains, desert, etc.
In my opinion, you can have a nice camp in this kind of places and celebrate your birthday in the most amazing way. This will be the best birthday present of your life.
Get yourself something new
When was the last time you bought yourself something new? If it has been many days, then this is the best time you can get yourself something new. For example, if you are planning to buy a car, then buy a car. By doing this you will make your birthday memorable.
I still remember when I became 18 my dad gave me a car on my birthday. I still remember that day not because I was 18 but because that day my dad gave me a car. So if no one gives you something unforgettable, then go ahead and get yourself a gift.
