Learn to fly or stay on the ground ?

[yanecek]

Hi there.
I’ve been reading pprune forum for a while, talking to people who are doing modular course and now I’m making decision whether I want to invest all my savings and do first bits (medical, ppl, hours, and ATPL theory) while working full time to make money for the rest to become commercial pilot.
My biggest concerns are:

How much time will I need to complete zero to hero while working full time?

Should I change my office IT 9-5 job to 4 on 4 off pattern job in order to have more time for learning to fly?

Is 30 years a bit old to start all that ?

I went to see . They sound trustworthy, got good opinions on various forums, the nearest to where I live, but still not sure if there is a better option ?

Thanks for any help
