Why are there inspiring commencement speeches at the end of our tertiary education

We're finished , that encouragement , and words of Inspiration would've helped me a lot more during the middle of my studies.
Not at the end , because it's useless , it has less meaning to me now that I've got my own story of struggle , not that I'm disrespecting other people's stories but I would hold up a lot stronger discussing mine over someone else's.

I could of used these words of inspiration when I was really lost, when maybe they could've held a slight incentive to carry out a full frontal form of determination

Maybe when my photoshop indesign quits on me and loses some of my work and I'm at the brink of tears, that's when I think I need these inspirational speeches.

Not because they're a cliche but because I feel that I could relate to them in some way.
Those speeches always share fragments of the downs as well as the ups, I like to hear those downs so I know it's not just me.
I like to hear those downs because there is someone else who knows my pain.
Because there is someone else that possibly thought "well hey , maybe this is it" but only for a second while they continued trying to recover lost work, an unpopular idea , or just recovering from a  bad day.
The one thing they didn't do though, Was to give up

I could be the most terrible student but as long as I'm trying my hardest and my best I think I'll be okay

Yes it's a kick in the face when your best isn't good enough, but hey! that's life. Just think, life doesn't have a grading system
