The Change 

A friend of mine who was quite and hard working student used to stay home and spend hours working and have no fun. even you could call him a real nerd.

But nowadays he has   changed. He has started taking music classes and to learn play a musical instrument and  wants to be a professional on that. I  hope he'll be a great musician.

He also has started to go gym regularly. He takes fitness classes and he'll be in great shape and a very attractive athlete soon.

next year, he is going to propose the girl who he loves. He will be spending his time with his wife and will be very busy.

(a bit changed but elegant I think ;-))
