The limit is the new target you set every new day,young one.
May the power of non-stop-gathering-because-you're-level-3 be with you.
It's better to be silent and be thought a fool than to speak and remove all doubt. What's even better is to weaponize your words to destroy anyone who dares challenge you.
As i know there is not a limit, so just calculate how many u can gather one day
P.S. Are you sure you will stay in front of the pc all the day gathering resourses ?
Don't be jelous of others, try to care about yours, only after that you will understand what you really have. P.S. Is very very very hard but i will try my best
