"Big Bang Theory" star Mayim Bialik thought she was helping Millennials when she offered tips on how to avoid burnout, but the target audience instead found it offered more condescension than useful advice.

In a video posted to her YouTube channel Thursday, Bialik, 43, offers a series of ideas she thought would benefit Millennials (people aged from 23 to 38, according to Pew Research). She advised them to "slow your roll," "lower your expectations," and "buckle down."

Bialik was down with the Millennial preference for text messages and email over phone calls but she may have lost them when she suggested they read Douglas Coupland's book "Generation X" for insight into that age group, composed of adults aged 40 to 54.

"I assume you haven't read (it) because they haven't made a movie of it," she cracked.

In the "Lower your expectations" section, she took them to task over using words like "detox" and "self-care" when asking their bosses for time off.

"Self-what?" she laughed. "That has to be a term that you Millennials created."

She also knocked them for giving unsolicited feedback about what they didn't or didn't like about their jobs.

"This makes adults older than you crazy," she warned.

Even Bialik's devoted fan base wasn't buying her advice.

"I normally love your content but this seemed really unnecessarily generalized and insulting," one person commented. "I’m really disappointed as I usually look forward to a new video from you.﻿"

"This seems a bit reductionistic," another chimed in. "Rather than giving practical advice for avoiding burnout, this just seemed like a list of ways that millennials aren't fitting into the world that older generations designed for them."

Even her non-millennial fans gave the video a thumbs-down.

A "nearly 40"-year-old fan wrote they usually admired Bialik's perspective. "Not so much, this time. Condescending/patronizing a group of people for being who they are, based on the previous generation that raised them....seems a bit out of touch."

Bialik responded to the outcry Friday in the comments section of her video, apologizing and prompting critics to help her tackle the subject properly.

"I may have missed the mark in this video," she commented. "I want to learn, and make a follow-up video, so I would love if you sent me specific issues about millennials you’d like me to address and expand my knowledge on. Send articles, experiences – anything you think would help. I’m sensitive to your concerns and appreciate the feedback I’ve gotten so far.﻿"
