Prepositions followed by verb+ing Hi all. My doubt is, always after prepositions "in", "at" and "on" the preposition is followed by verb+ing? If no, which are the exceptions? Do you mind show me an example? Thanks so much :)

My plans to 2016 It's always the same thing, when a new year starts we do plans like study more, make a diet, do more exercises but almost always in the end of year we are as we begun. But in this year will be different. I trace my plans and I'll do what I planned. In 2016 definitively I'll be fluent in English. Yeah, it is my main goal. I use English everyday but still I'm not fluent because is a very technical English and sometimes I feel unconfortable to write/speak with my job partners. My second goal is lose weight. I'm not very fat but is better to my health that I lose weight. I'll make a diet and do exercises everyday. I think that theses are my plans for 2016, and I hope that in 2017 a have differents plans and that you turn true yours. Thanks :)
