Learning Maths in your 40s?

I like the concept of maths in primary school and always thought it was fun. Then I struggled with secondary school and often gave up and just got passing grades, then I did passed the necessary amount in college for the courses I was doing.

At the back of mind, it was always something that bothered me and I often thought about studying part time at my own pace with online courses, just to have a better understanding of it.

Has anyone ever been in similar situations?
