There is nothing wrong with looking good, but first you must accept yourself for who you are, faults and all in order to know your limitations and start from there.
Ask yourself this question, who do I want to look like in the long term perspective. I'm sure if you can answer this, you'll find a look that you can manipulate till the end of your days in the view of your liking.
You are like water, you limit yourself to the container that forms your physical form.
The rest, you just need to upkeep that form.
