I can't handle it anymore

Opportunities come and go. Not all the time they are there but there is really a time that opportunities are flooding that I can no longer handle it anymore. Sometimes, I let it expire and some I let my brother make my opportunities especially if I’m busy at school. There are also times that I skip meal or sleep late just to finish all my opportunities. But if I don’t know how to make the assignment, I just let it expire.b
