I think that when you grow up you should make it a priority and perhaps a full time occupation to be fat. Or at least choose a profession which will not pull you away from this goal.
The benefits thereof are many-fold. Most importantly you do not want people to judge you by your looks, but rather by your insides. To this end it is important that you try what you can to minimize the options. Being fat will keep you warm in the winter. It also makes it very easy to operate those office chairs that go up and down.
