>>55353339There is literally nothing wrong with imagining yourself but with Pokemon, it's the premise that this entire setting is built on. However, in recognizing that you are recreating yourself, you have achieved an important first step in the creative process: you have become self-aware. It can be hard for some people to imagine being someone else, and that's okay.
In my own experience, the best cure for self-insertism is to let the personality "drift" until it becomes its own entity. Take a part of yourself and stretch it, and the rest of you will be pulled along too. What if I had a quicker temper? How would that influence the rest of my behavior? Would I try to rein it in, or would I just end up finding something else to be angry about? What would I do differently if I was influenced by Variable-A instead of Variable-B? Where would I be today if I didn't have someone like Variable-Z in my life and instead had Variable-P, where P = your mons?
Do you settle into a quiet and stable life, or do you rally against the norm and live free in the wild, eking out an existence off of odd jobs and prize money; carried along the winds as far as your skills will take you?
What about your home? In real life, Cadman Park is a tiny little row of trees that could hardly fit a deer. In the Pokemon world, it's the sprawling Pinwheel Forest where giant centipedes lurk and a legendary goat retreats to when it needs some me time. What if the soccer field by your house was actually a vast prairie where Fire-Types go to sunbathe? How would that affect your weekly habits?
These are the questions you should ideally be asking yourself. Expand your mind, expand your limits.
