Do you have that summer job that EVERYBODY else has? Or do you have the summer job that 15-year-olds can do? Do people say that you have an easy job? Will this job ever help you in the future? These questions are the worst to hear about your "basic" job.
Sometimes having a basic job is the best job. You don't need to have that fancy internship that goes with your major or that high-paying job that has room for advancement. Sometimes all you need is a job that by the way is not always easy, but a job that pays money and you can just get some experience working. Whether this is your first job or just a job that you go back to every summer, it is a great job for you to have.
Do not believe what people tell you about your summer job because most likely, they do not even have a job. Be happy in whatever you decide to do over your vacation. Have fun during your summer and do not change your happiness for anybody else. You have a lot of time to get that boring internship done, but for right now have fun being a camp counselor or a lifeguard or just working at a snowball stand. Do what you want to do!
