Dude, Don't fret. I know two work colleagues who moved from industry to Consulting in their mid 30s. One of them moved just last week! Sure, they might be reporting to some snotty, pretentious young wannabe who needs a good slapping, but hey, we all have to put up them. As the previous commenter stated, put your heed down, be helpful, be proactive, and before long you will have accelerated past him/her before he/she could say 'yeah but no but'. Take each days as it comes.
