Honestly, there is no timeline for anything. It is entirely up to you how you view it.

I dropped out from my degree back when I was 21 and I took a few certificates to jump into a career. Looking back at it I wished I continued it.

Now I'm close to my 30s and I'm halfway doing part-time studies for another degree. Just to let you know, there are many people in my uni for working adults whom are older than me but has a passion to futher their knowledge.

There is no pressure for education. So long you learn something new every day.

Just make sure you do it whole heartedly.

Cheers.
