Being a student of course needs lots of efforts especially if you take more credits. It takes me several weeks to be used to it. To be honest, even my friends take less credits than I do, they seem stressful than me. Arrgghhhh!!!".."Bangun"..
That were things said by them especially at night.
I might confuse you currently but let me straightly point out the message.
1. Be grateful as you've given chances to have "more" but give "less".
2. In matters of facing probs, look at those who have bigger probs than you do.
