Hi Paula, I'll give it a go, hope it helps.

I'm studying at the moment and hope to graduate in two years, after which I'd like to be an Engineer. I'd love to travel and explore South America and have plans to do some volunteer work in Chile during the summer next year.

My personal goals include going to the gym next semester and sticking to a workout routine. I believe that getting my body in shape will make me more enthusiastic about participating in physical activities. I also want to train my mind through meditation and just being more mindful. Hopefully, in a couple of months, I'll see some improvements in concentration and be able to control my anxiety levels better.

Hahaha I don't even know what the future perfect is!!!
