Imagine someone is living a hard life because they have to save their income to invest in a very worthwhile field that can be very helpful in their future financially. You want to sympathize with them.
Or (at least in our language)
Imagine you want to sympathize a university student who is going through think and thin to achieve a degree at a very good college and in a good major which can guarantee some valuable job opportunities for them afterwards.
In the both cases above, one can use a multilateral proverb in our language which says: "You can pay your dues and enjoy the fruits of your labor for the rest of your life."
The only proverb which I found in a domestically written book, was:
- Short term pain for long term gain.
However, even if it works I doubt if it is something that sounds natural to an American.
I was wondering if you could help me with this case and let me know what is the best way to convey the massage in my question.
