Many of us finish our studies first before we focus on money making activities as it's more easier and doing so won't affect our studies, so my only advice to the students right now is don't rush things but they should enjoy their youths first because they will surely regret it in the future if they won't.
But they can always opt to save money as much as they can.
So whenever they need it, they are not desperate where to find money.
But don't stress yourself in saving if you don't have it. Just live within your means.
Now, when the times comes you can afford to save money, then do it diligently.
Lucky if you can still keep some money while studying, not many students can do that these days.
