You could also try and get rid of the chip on your shoulder about people older than you getting on better than you in the workplace.
Indeed.
I was a mature student myself.
I was the one who had to retake my A-levels* aged 40 because when I was actually at school my home life was so sh1t I couldn't study effectively.
I was the one who asked the questions the whole class was wondering about because the younger ones wouldn't ask in case they made fools of themselves.
I was the one who got my work in as early as I could because I also had a disabled husband, and a house full of kids and dogs to worry about so I didn't dare risk leaving anything to the last minute.
I was the one who wasn't out on the piss every night and panicking at the night before deadline because I hadn't done the reading, let alone written the essay, and now I couldn't get hold of the books because other students in similar mode had got them out of the library.
I was the one who knew that this was probably the last chance I had for a decent education, and was I hell going to waste it.
And while I wasn't "friends" with the tutors, in the sense that I didn't share hobbies or go for a drink with them, I probably did find it easier to talk to them in a relaxed manner just because most of them were nearer my age.
*I took 4, in a year, in my spare time, and achieved 3-A stars and a B. Nobody did me any favours by feeling sorry for me because I was "old", or they were "pally" with me. I worked my arse off to get there and make a good job of it. You'll find that most mature students are the same. They know it's now or never for them.
