1. I can get a lot of money by my 30 th birthay by inviting my grandparents wich will give me money.
2. In this case,i can get a job for a short period, then when i have enough money i can buy the phone.
3. second hand products have a lower price than new products,so that's why it is a good idea to choose second hand products.
4. if you want to get some money,you can be a waiter. i think the salary is enough for this job.
5. No,i don't think this is a good idea,because nobody want to spend money on something that wouldn't make them happy or proud of theirselves. You should better buy something that u need such as: food,clothes, books etc.
