Writing on my tea mug

[abcdefg]

Bought a new double-walled 双层 tea mug recently. Having trouble making sense out of the inscription. Pretty sure the first two characters are 天道 and the last one is 勤，but am stuck on the third one, which hopefully gives the inscription some meaning that is relevant to drinking tea.

 

One wild guess was 醆, but I'm not sure it fits, unless it's part of a quote.

 

Any thoughts? Thanks in advance!

天道酬勤

Terrific, @imron -- Many thanks! That's a good idiom. Especially for drinking tea while studying or engaging in other scholarly pursuits. I will use a different mug if just watching a soccer match on TV.

Ah, some would consider a soccer match just as lofty an ideal.
