WELL THAT DIDN'T GO WELL.
If you have opportunity and motivation and a diverse set of interests, you're probably going to end up with a lot of cool experiences under your belt. If you're an autodidact and hold yourself to a high standard with whatever you pursue, you may end up with a knowledge base, skill set, and life experiences that apply to a very wide range of circumstances before long.
You're not parading yourself around as the World's Greatest Part-Time Uber Driver, as far as I know, Stinkles. There's definitely a line that can be crossed into arrogant self-absorbed dickbaggery, but I tend to see it coming from folks who lose sight of the privilege of their circumstances (or, typical of trust fund kids, who never had sight of it to begin with).
Everyone's cherrypicking the interesting 1% of their time to throw onto social media, so, hey, if you have more than 1% to share, it doesn't automatically brand you an asshole. There will always be someone bitter about someone else's successes, no matter how you live your life. The key consideration is that there's an unabashedly dickish route, an unrealistically saintly route, and an entire spectrum in-between where you can probably operate with some nuance, yeah?
You can leverage your circumstances not just to succeed at what you set out to do for yourself and let everyone know how awesome you are. With the right perspective, you can use the space you're operating in also to relate to people from all walks of life, give sound advice and assistance to people you wish to, help lead and motivate others, and balance out personal enrichment and success and hedonism by designating a percent of your time and resources toward giving back in some way.
Live it up. Just don't forget your origin story, and how precarious it probably was. Don't assume you're better than someone because of what you see in the mirror, because there are very bright, very capable people all around you who will never have an opportunity to shine thanks to the whims of fate or the burden of responsibility. Is someone who stayed behind in their hometown to take care of their sick parents or disadvantaged siblings or accidental teenage kid less awesome for having chosen that path? What about someone who worked twice as hard with half the advantages, just to carve out a small piece of their dreams? What about someone who find solace and contentment in the little things? None of those are lesser paths.
