Dear Tom,
I’m so surprised to hear that you have decided to drop out of school. I don’t think it is wise to do so. Most large companies are in need of people with knowledge, so how can you find your dream job if you choose to drop out of school so early? My elder brother once had the same idea as you, but he finally chose to study first, and now he has gained his dream job. I personally think it would be better for you to finish your studies first. Being knowledgeable and skillful helps you a lot when seeking a job. I hope you will take my advice into account.
I am looking forward to your reply.
Yours,
