Maybe try turning a hobby into a business? I don't mean Tycoon status, but if you can get there.... yay? Just sort of a side earner and something you enjoy doing at the same time.
If you don't have a hobby that could be profitable, think of something new you'd like to learn that might be a nice little earner. Learning a new language to be an interpreter. A topic you could make a related blog about and earn from blogging.... just don't go for recipes, so many of those out there already. Many things you could do, just requires a little imagination and some internet research.
I think if I were at the beach though the last thing I'd want to do is be on my computer / Clixsense some more.
The beach is for taking time out.
I like dutch's idea, that's something I've thought about doing myself.... doesn't profit me in anyway, but helping others less fortunate kind of puts things into perspective for you and can make you feel good.
