I think you like being a martyr

Anyhow just to say it
But Emz, some skills take longer than others.
Different people get different skills faster or slower

In fact builders do take awhile. Strategy would suggest if you want elders especially when someone is old enough to work put them on building first, once they master it, it is easier to get the other 2. Get research last because they dont have to go far to work and succeed. This game adds a lot more strategy into it if you want to succeed well. But yea master builders take awhile, but far from impossible. I have like 15 of them.
