Sidneyraz told Bored Panda he decided to start this series after people really liked his video 'Here's something you should know about being in your 30s. It's better than your 20s.'

"My most popular videos are ones that have to do with the most common items that people use. Travel pillows, English muffins, trash bags, plungers, and so on," the creator explained. "We all use the same things every day and [without questioning them] because that's how we were taught, but we have no idea why or if it's even right. So when I post a video showing a different way, it blows minds."

Of course, Sidneyraz thinks there's more to this life stage than life hacks. "We tend to experience both heartbreak and true joy before our 30s too. There are large ups and downs but, hopefully, they help us to be more empathetic people. They’re hard lessons but needed."

"I’m learning all these things too and I don’t want anyone to feel as alone as I have in the past when I didn’t know something [older folks understood quite well]," the TikToker added.

I think it's no coincidence that Sidneyraz started this series in his early 30s.

Robert Taibbi, a licensed clinical social worker with 48 years of experience, primarily in community mental health, said that research on adult development tells us that our lives move in waves: several years of relative stability and focus, then several years consumed with bursts of unrest.

"Part of the challenge of [the early 30s] comes from the fact that your life has actually settled. For many of us, the 20s were filled with tremendous changes – finishing college or some higher ed, deciding on some major or career path, venturing forth. If not doing more schooling, moving into jobs that may or may not become a possible career. Relationship-wise, either a lot of dating or even marriage. Regardless, lots of activity and anxiety," Taibbi wrote in Psychology Today. "Now you are likely somewhat settled – in the marriage or the job/career. You have the time to catch your breath and take stock of where you are in your life." Which can include creating a TikTok account and telling others what you've learned!

However, that doesn't mean that life gets easy when you enter your fourth decade. In fact, this time can come with added pressure to hit adult milestones.

"One of the main words I listen for in a session is 'should,'" Megan Bearce, who sees many 30-somethings, told Vox. "I should have a child, I should be married by now, I should love my job.".

A good example of this is a study where researchers asked folks in their 30s and 70s which of these groups they think are happier. Both groups answered the 30-somethings, but when they were asked about their own subjective well-being, the 70-somethings scored higher.

So when you hit your 30s, remember that it's probably a good idea to not only give but seek some good advice as well. And don't compare yourself to others. Continue building your life. You're on the right track
