Ponder this:
What would your future look like if you didn't go to university?
What would your future look like if you did go to university?
For both, what would you do? What could you do? What options for work/work progress would potentially be available?
Also, don't concern yourself about being to old or "what society thinks"; it only matters if you allow it to bother you.
If you want to do it, don't make excuses and just got for it.
